These were dropped from variables.nix by a stash/merge conflict
resolution on main (commit fb6ee27) that kept the new wifiSsid value
but discarded the two disk-path variables entirely, leaving unresolved
`<<<<<<< Updated upstream` markers in an intermediate commit before
being cleaned up. modules/disko/baremetal.nix references both directly
with no fallback, so baremetal-gui has been failing to evaluate on main
since that commit ("attribute 'guiRootDisk1' missing") -- confirmed by
cloning main fresh and evaluating config.disko.devices.disk.disk1.device
directly.
This commit is rebased onto latest main (through "updated secrets",
which registered baremetal-gui's real sops recipient) rather than the
older base this branch started from.
Moves the auto-installer's shell script from an inline Nix string in
modules/installer/common.nix to scripts/installer/auto-install.sh, a
real, version-controlled, directly-editable/shellcheck-able file.
common.nix now wires it in with pkgs.replaceVars, substituting the one
value that actually needs to come from variables.nix (lanDomain) --
every other `${...}` in the script is a literal bash reference, left
untouched. replaceVars fails the build if any @name@-shaped placeholder
is left unsubstituted, so a typo'd or renamed variable is caught at
eval time rather than silently shipping broken.
Verified: built the substituted derivation and diffed it against the
source template -- identical except for the one substituted line, no
leftover unsubstituted placeholders. Full codex-maintenance.sh (secret
grep, fmt, statix, full eval of every host/package including the
installer/pxe artifacts that consume this) passes clean.
Wires everything staged so far into a real flake target:
- modules/platforms/baremetal.nix (new): the bare-metal platform module,
composed from a real nixos-generate-config run on the actual gui-host
hardware (AMD CPU, ahci/xhci/usb storage -- modules/hardware-configuration/baremetal.nix).
Enables hardware.enableRedistributableFirmware (real wifi/GPU/microcode
firmware VMs never needed), amdgpu as the Xorg video driver plus
hardware.graphics for Mesa OpenGL/Vulkan, and imports the ZFS RAID0 disko
layout + modules/services/zfs/enable-service.nix for root-on-ZFS boot
support.
- flake.nix: new baremetal-gui target, reusing hosts/nixos/host.nix (same
identity already shared across linode/proxmox/lxc-gui).
- hosts/nixos/host.nix: added networking.hostId, required now that a ZFS
root pool is in the picture.
- variables.nix: guiRootDisk1/guiRootDisk2 filled in (/dev/sda, /dev/sdb --
only used transiently at disko-format time, same as modules/disko/proxmox.nix's
own plain device path). wifiPassword removed.
- modules/networking/wifi.nix: reworked to pull the wifi password from a
new sops secret (secrets/gui.yaml, wifi-password) instead of a plaintext
variable -- NetworkManager's ensureProfiles renders `psk = "$WIFI_PASSWORD"`
literally (nixpkgs' own documented pattern for this) and envsubst-expands
it from a sops-rendered EnvironmentFile at activation, so the real value
never touches the Nix store, only /run.
- .sops.yaml: new secrets/gui\.yaml rule, admin + the currently-registered
lxc-gui recipient (the only gui variant with a provisioned host key so
far -- whichever variant is actually deployed next still needs
scripts/secrets/sync-host-keys.sh run for its own recipient).
- README.md/CLAUDE.md: documented the new platform/target and its module
layout, per this repo's own drift-prevention note.
Verified end-to-end: nix eval of every existing target (nothing broke),
a temporary real nixosSystem build against the actual disko.nixosModules.disko
confirming the generated zpool create has no mirror/raidz keyword (genuine
stripe), and a temporary test SSID confirming the sops secret/template/
ensureProfiles chain renders correctly before reverting to blank/real values.
Full scripts/codex-maintenance.sh (secret-grep, fmt, statix, full-fallback
eval of every host/package) passes clean.
Adds modules/disko/baremetal.nix: two disks, each its own top-level
zpool vdev with no mirror/raidz between them (disko's zpool `mode`
defaults to "" for a plain stripe), ESP + systemd-boot on disk1. Device
paths are placeholders in variables.nix (guiRootDisk1/guiRootDisk2)
until the real hardware profile arrives.
Verified structurally by building a throwaway nixosSystem with the
actual disko.nixosModules.disko and reading the generated
system.build.formatScript: it emits `zpool create rpool ... disk1
disk2` with no mirror/raidz keyword, confirming a genuine stripe.
Not yet wired into any flake target -- that happens once the hardware
config lands and a new bare-metal platform module is added, per the
agreed sequencing.
Adds modules/networking/wifi.nix using NetworkManager's ensureProfiles
mechanism so the gui host associates to a known SSID on first boot with
no manual nmtui step. Credentials are placeholders in variables.nix
(wifiSsid/wifiPassword, both empty) to be filled in once the bare-metal
hardware profile is wired up — the module is a no-op until then.
The iPXE menu's "nixos" entry actually chain-loads this flake's own
custom auto-installer image, not a stock NixOS image — rename it to
"auto-installer" (label "NixOS Auto-Installer") so the menu says what it
boots, and set networking.hostName on netbootSystem to match, so the
generated system name (nixos-system-auto-installer-*) and staged
directory (/srv/pxe/http/auto-installer) agree with the menu entry too.
Add a second, genuinely vanilla NixOS minimal netboot image
(netbootMinimalSystem in flake.nix — nixpkgs' netboot-minimal.nix on its
own, none of modules/installer/common.nix's auto-installer wiring),
built from source the same way as the auto-installer image and exposed
as packages.x86_64-linux.pxe-minimal. Staged and menu-wired the same
way, as "nixos-minimal" (item, hostname, and directory all matching).
modules/pxe-boot/stage-installer-artifacts.nix is generalized to stage
both images via a shared rule-builder instead of one hardcoded set of
paths.
Verified: nix eval confirms both images' config.system.name matches
their menu entry/directory names, the pxe-boot host itself builds
clean with the new menu.ipxe, and the new pxe-minimal image was booted
directly under QEMU (kernel+initrd, no KVM) to a working login shell
with hostname nixos-minimal, no hang.
The netboot build composed ./modules/installer/iso.nix (which pulls in
nixpkgs' installation-cd-minimal.nix) together with nixpkgs'
netboot-minimal.nix. Both installation-cd-base.nix and netboot.nix set
fileSystems."/" via the identical lib.mkImageMediaOverride (mkOverride
60) priority - genuinely conflicting root-filesystem strategies
(ISO-by-label vs. netboot-tmpfs) at the same priority, and the ISO one
was winning. Every netboot boot hung waiting for a device that can
never exist outside a real CD/USB:
A start job is running for /dev/disk/by-label/nixos-minimal-...
Reproduced live: deployed a scratch lxc-pxe-boot on pve-test, pulled its
built kernel/initrd, and booted them directly with QEMU to confirm the
hang and capture full console output. netboot-minimal.nix's own chain
(netboot-base.nix) already imports profiles/installation-device.nix
independently, so common.nix's initialHashedPassword override still
applies correctly with iso.nix removed from this composition. Rebuilt
and re-booted the same way after the fix - full boot to a working shell
with SSH up, no hang.
Backs up a VM/CT on pve1 (snapshot mode by default, so the source stays
online), relays the archive to pve-test, restores it there with fresh
MAC addresses (--unique), and deletes both the source and relayed
backup copies afterward -- no ad hoc backup files left behind on
either node.

pve1.sweet.home is production; scripts/env.sh now also defines
PVE_TEST_HOST for a separate sandbox node, individually targetable via
--node/PROXMOX_HOST. Tooling defaults are unchanged (still pve1) -- the
new restriction (Claude defaults to pve-test unless explicitly told to
use pve1) is documented as policy in CLAUDE.md, not enforced in the
scripts.

The kernel's NFS client filesystem doesn't set FS_USERNS_MOUNT, so mounting
NFS from inside any non-init user namespace -- exactly what an unprivileged
LXC container's UID-mapped root runs in -- is rejected at the VFS layer
with EPERM, regardless of Proxmox's mount=nfs;nfs4 container feature (which
only patches the AppArmor layer). Confirmed live on the redeployed lxc-docker
container: TCP to the NFS server's port 2049 succeeds, the server's export
table matches the container's IP, and mount.nfs: Operation not permitted
still fires immediately with no corresponding denial anywhere in the
server's own logs -- a kernel-level rejection that no amount of DNS/
automount/export tweaking (this branch's earlier commits) could ever fix.
modules/platforms/lxc.nix now keys proxmoxLXC.privileged off hostName
("docker" -> true) rather than a blanket false, since build-types/docker.nix
is also composed for linode-docker/proxmox-docker, which don't import
proxmox-lxc.nix at all -- setting this option there would break their eval.
create-proxmox-resource.sh reads the value back via a new
flake_target_lxc_privileged helper instead of hardcoding --unprivileged 1,
so the two stay in sync automatically for every lxc-* target.

create-proxmox-resource.sh's `qm create` never passed --agent, so despite
services.qemuGuest.enable = true being set on every host, Proxmox never
created the virtio-serial channel the guest agent needs -- qm guest exec
and the UI's IP-address display silently never worked for any VM this
script created. Found while live-testing every lxc-*/proxmox-* build type
against pve.sweet.home for an end-to-end flake audit.
Also registers a fresh sops age key for lxc-gui (no prior registration
existed), generated while testing that target live -- needed before
lxc-gui can be deployed with working secrets.

The previous commit's networking.search fix was wrong. Confirmed live
on lxc-docker (vmid 105) after redeploying with it: `resolvectl query
server.sweet.home` started failing again, even though
`resolvectl query --interface=eth0 server.sweet.home` still resolved
correctly to the right IP via the LAN's real DNS server. The debug log
showed why -- adding a *global* search domain via networking.search
gave systemd-resolved a domain-matched but server-less "global" scope,
which it now prioritizes over eth0's correctly-configured scope for
every "*.sweet.home" query, silently sending them to public fallback
DNS (1.1.1.1 et al) instead, which of course returns NXDOMAIN for an
internal-only name. Bare single-label names (e.g. "server") were never
going to work either way -- systemd-resolved only ever tries LLMNR for
those, never DNS search-suffixing, regardless of configuration.
Reverts the networking.search addition and instead has
modules/docker/mount-data.nix build each NFS device string from
"${vars.nfsServerHost}.${vars.homeDomain}" (a plain FQDN, no dependency
on search-domain behavior at all) -- the same pattern
modules/raspi/mount-data.nix already uses for the Raspberry Pi's share
and for the identical reason.

Cross-host references throughout this repo (vars.nfsServerHost,
vars.nixCacheHost, vars.dockerHost) are bare short names, not FQDNs.
Resolving them has always depended on whatever network stack happens
to be in play picking up the DHCP-advertised domain as a search
suffix -- NetworkManager does this by default, which is why it went
unnoticed everywhere else, but LXC containers force-disable
NetworkManager and get their systemd-networkd config written directly
by Proxmox instead, which never sets one.
Confirmed live on lxc-docker (vmid 105) after today's earlier fix for
the automount/mount=nfs bugs: systemd-resolved had no search domain
for eth0, so "server" failed to resolve ("Name or service not known")
while "server.sweet.home" resolved fine via the same DNS server --
every NFS mount in modules/docker/mount-data.nix was still failing.
networking.search sets systemd-resolved's own Domains= globally
rather than depending on the per-link DHCP path, so it isn't at the
mercy of whichever component owns a given host's interface file.

CI was running a full eval of every host + package on every push/PR,
which was slow enough to routinely time out the Gitea runner. Default
mode now diffs against a base ref and scopes nixpkgs-fmt/statix/eval to
the files that changed and the hosts/packages they can affect; a change
to flake.nix/flake.lock/variables.nix/modules/common/* (or any other
modules/*.nix outside platforms//build-types, whose blast radius isn't
inferable from the path) falls back to evaluating everything. The old
full sweep moves behind --full-check, which CI never passes; --dry-run
adds build-planning on top of whichever scope is active.
Also trims codex-setup.sh's redundant full host eval loop -- that's
what codex-maintenance.sh is for; setup should just install tooling.
variables.nix's nixCacheHostKey no longer matched nix-cache's actual SSH
host key (confirmed via ssh-keyscan against the live container), so every
declaratively-configured client's programs.ssh.knownHosts trusted the
wrong key -- distributed builds would fail host-key verification. Also,
modules/nix-cache/remote-builder-client.nix hardcoded sshKey to
/root/.ssh/nixremote, but the `server` host only has its own default
/root/.ssh/id_ed25519 installed (confirmed live via qm guest-agent) --
that file was never even present, so the build machine config pointed at
nothing. Standardize on each client's own default identity, matching the
per-host-key pattern vars.remoteBuilderAuthorizedKeys already uses instead
of a shared/differently-named keypair, and add
scripts/secrets/sync-nix-cache-host-key.sh (wired into
codex-maintenance.sh's --check) so the host-key drift doesn't silently
recur next time nix-cache is rebuilt or recreated.

Following the existing per-client-key pattern in
vars.remoteBuilderAuthorizedKeys (one entry per host's own default root
key, not a shared dedicated keypair -- docs/nix-cache.md's "./nixremote"
filename is just a generic placeholder in the instructions). This box
had no entry yet, which is why its earlier `ssh-copy-id nixremote@nix-cache`
never stuck: nix-cache's nixremote authorized_keys is NixOS-declarative
and gets overwritten on every rebuild.
Public key only; requires a nix-cache rebuild to take effect.

scripts/ had grown to 10 top-level scripts covering three distinct
concerns (sops/age + SSH host-key management, Proxmox deployment, and
repo-wide bootstrap/CI) with no grouping. Move the key-management scripts
(backup-admin-key.sh, rotate-admin-key.sh, prepare-host-key.sh,
sync-host-keys.sh) into scripts/secrets/, and the Proxmox scripts
(create-proxmox-resource.sh, configure-nix-cache-client.sh) into
scripts/proxmox/; leave env.sh, codex-setup.sh, codex-maintenance.sh, and
bump-nixpkgs-release.sh at the top level (frequently hand-typed or pure
shared config) and scripts/lib/ as-is.
Updates every cross-reference: each moved script's repo_root computation
(now one directory deeper), shellcheck source= directives, inter-script
paths (create-proxmox-resource.sh's call into sync-host-keys.sh and its
remote bootstrap of configure-nix-cache-client.sh on the Proxmox node),
and every doc/module mention (CLAUDE.md's Scripts section reorganized to
match, README.md, docs/auto-installer.md, docs/proxmox-images.md,
modules/installer/common.nix, modules/platforms/lxc.nix). CI workflows
need no change -- they only invoke codex-maintenance.sh, which didn't
move. Verified via bash -n, shellcheck (no new warnings beyond the
pre-existing SC1091/SC2029/SC2095 baseline), and live dry-runs of
sync-host-keys.sh --all and create-proxmox-resource.sh --list from their
new paths.

scripts/backup-admin-key.sh, rotate-admin-key.sh, and sync-host-keys.sh
each independently resolved sops/age's default key-file path, derived an
age pubkey from an identity file, and (two of them) ran `sops updatekeys`
the same way -- now shared via scripts/lib/sops-age.sh. Also extracted the
"type X to confirm" prompt duplicated across create-proxmox-resource.sh
and sync-host-keys.sh into scripts/lib/confirm.sh. Pure extraction, no
behavior change -- each call site produces identical commands/output to
before.

.sops.yaml's &lxc-nix-cache anchor was rotated (commit b3c8145) after
today's LXC rebuild, but secrets/nix-cache.yaml was never re-run through
sops updatekeys -- it stayed encrypted for the pre-rotation key. Per
docs/nix-cache.md and docs/auto-installer.md, sops-nix decrypt failures
are silent: cache-priv-key never materialized, nix-serve had nothing to
bind its secretKeyFile to and failed to start, and nginx proxy_pass had
no upstream -- the 502 Bad Gateway seen from clients.
Confirmed the new key matches the currently-deployed host by deriving
the age identity from host-keys/lxc-nix-cache_ssh_host_ed25519_key.pub
via ssh-to-age and comparing to .sops.yaml.

Run it once, right after a node's first-time Nix bootstrap (not on every
invocation, and not inside codex-setup.sh/codex-maintenance.sh themselves),
so a freshly-bootstrapped Proxmox node substitutes from and can offload
builds to nix-cache on every subsequent run. Non-fatal on failure -- the
build still proceeds, just without nix-cache.

Non-NixOS machines with just the Nix package manager installed have no
module system to pick up modules/nix-cache/client.nix, so this edits
/etc/nix/nix.conf directly (extra-substituters/extra-trusted-public-keys,

falling back to cache.nixos.org when nix-cache is unreachable.

Per-run tooling verification (added in the previous commit) was hardcoded

Two bugs found running scripts/create-proxmox-resource.sh against a real
Proxmox node for the first time:
- The Nix installer's single-user root path still shells out to `sudo`
to create /nix even though it already detected it's running as root,
which fails outright on a minimal, sudo-less Debian/Proxmox node.
codex-setup.sh now pre-creates /nix itself so that branch of the
installer is skipped.
- ensure_remote_repo() only ran scripts/codex-setup.sh right after a
fresh git clone, so a bootstrap that cloned the repo but then failed
installing Nix (exactly the failure above) left every subsequent run
silently building with a `nix` that was never actually installed,
since the repo already existing skipped tooling setup entirely. It
now checks `command -v nix` (via the same ensure_nix_profile used
elsewhere, since a non-interactive ssh session won't otherwise have a
single-user install on PATH) on every run and re-bootstraps if it's
missing. Both remote build heredocs also now source
scripts/lib/nix-bootstrap.sh themselves for the same PATH reason.

create-proxmox-resource.sh no longer builds locally and scp's a
multi-gigabyte image over -- it now clones/pulls this repo onto the
Proxmox node itself (bootstrapping build tooling via the existing
codex-setup.sh on first use) and runs the nix build / disko image
script there, staging the result straight into the node's own import
directory. host-keys/ (gitignored) is copied over separately since a
git pull doesn't carry it. --image still uploads an explicit local
file for the case where you don't want a build at all.

--allow-duplicate-host previously just skipped the existing-resource
check entirely, so re-running e.g. --type lxc --host docker while an
lxc-docker container already existed created a second container
sharing the same hostname/identity instead of replacing it -- both
then fight over DNS/DHCP for that hostname, and it's easy to end up
testing the stale one without realizing.
Now splits matches into "exact" (same --type as the one being
created, e.g. another lxc-docker) and "cross-type" (a different
platform sharing this host identity, e.g. a proxmox-docker VM
alongside an lxc-docker container -- a deliberate, valid coexistence
this script has never managed and still won't). Only an exact match is
destroyed and replaced, after typing the hostname back to confirm; a
cross-type match is always left untouched. Without
--allow-duplicate-host, both cases still refuse to run exactly as
before.
Verified live against pve.sweet.home: correctly split VMID 103 (a
stopped proxmox-docker VM, cross-type -- left untouched) from VMID 105
(the running lxc-docker container, exact-type -- flagged for
destroy+replace), and confirmed the destroy prompt safely aborts on a
non-matching confirmation, leaving both resources untouched.
Two compounding bugs, confirmed live on the running lxc-docker
container (vmid 102 on pve.sweet.home):
1. x-systemd.automount never works inside any Linux container --
systemd logs "Starting of <unit>.automount unsupported" for every
share and never mounts them. modules/docker/mount-data.nix and
modules/raspi/mount-data.nix now key off config.boot.isContainer
(set true by nixpkgs' proxmox-lxc.nix) to mount eagerly with
`nofail` there instead, while VM-based docker targets keep automount
unchanged.
2. The container's Proxmox `features` never included `mount=nfs`, so
AppArmor blanket-denies the nfs/rpc_pipefs mount syscalls NFS
needs ("permission denied"). scripts/env.sh's
PROXMOX_DEFAULT_LXC_FEATURES now includes mount=nfs;nfs4 for future
lxc-* containers -- the semicolon required quoting the --features
value in create-proxmox-resource.sh's remote pct-create command,
since it's sent as a raw string for the remote shell to parse and an
unquoted `;` would be read as a command separator.
The already-running container needs a matching `pct set --features`
plus a restart to pick this up -- that's an operator step outside this
repo.
Distributed builds failed with "Host key verification failed" on any
client that had never manually SSH'd to nix-cache before, since
nothing populated root's known_hosts for it. Wire nix-cache's host
public key into programs.ssh.knownHosts via a new vars.nixCacheHostKey
so every client picks it up automatically on rebuild.

lxc-* hosts need NIXOS_HOST_KEYS_DIR + --impure to bake in a pre-seeded
SSH host key, otherwise sops-nix's .sops.yaml recipient never matches
and every secret permanently fails to decrypt on first boot. That
invocation is easy to forget, so wrap it as `buildImage <flake-target>`
alongside the existing Switch-nix/Test-nix helpers.

The reachability check used `cat < /dev/tcp/${NIX_CACHE_HOST}/22`, which
blocks forever reading for EOF that never comes -- sshd sends its banner
and then holds the connection open waiting for the client to speak next.
Every single check hit the 3s timeout and reported "unreachable"
unconditionally, regardless of whether the remote builder was actually up.
Confirmed live: a plain TCP connect (`exec 3<>/dev/tcp/...`, no read)
returns in ~60ms against a healthy nix-cache instead of always timing out.
Fixing that exposed a second, previously-dormant bug: `printf -v
NIX_EXTRA_OPTS '%q ' "${NIX_OPTS[@]}"` on a genuinely empty NIX_OPTS array
still runs one format pass and yields the literal `'' ` rather than an
empty string. A subprocess (e.g. sync-host-keys.sh) reusing this
process's decision via `eval "NIX_OPTS=(${NIX_EXTRA_OPTS})"` then rebuilt
a 1-element array holding an empty string instead of a 0-element array,
which broke `nix-shell "${NIX_OPTS[@]}" -p <pkg>` with a bogus positional
argument the moment NIX_OPTS was legitimately empty (nix-cache reachable)
-- something the first bug had made impossible to ever hit before.
Also adds a couple of retries (1s apart) to both checks as a secondary
safety net against genuine multi-second blips, on top of fixing the
checks themselves.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
The tarball/disko-image build previews were hardcoded strings that never
included ${NIX_OPTS[@]}, so --dry-run always showed the same "would build"
command whether nix-cache's substituter/remote-builder got disabled by
nix_extra_opts's reachability probe or not -- the actual (non-dry-run)
build commands already applied it correctly, only the preview lied.

services.beszel.agent runs under DynamicUser=true with ProtectSystem =
"strict" and no StateDirectory, so /var/lib/beszel-agent -- where the
agent persists the fingerprint that locks its hub pairing to this
machine (github.com/henrygd/beszel/discussions/1542) -- was never
actually writable. Every restart silently failed to persist it and
regenerated a fresh one in memory, permanently desyncing from whatever
the hub had on record after the very first successful pairing. Affects
every host importing modules/beszel/enable-agent.nix (nix-cache, server),
not just full container rebuilds.
Found via nix-cache showing "fingerprint mismatch" after being rebuilt
post-outage; confirmed server was silently exposed to the same bug, just
hadn't restarted since its first pairing. Fixed by declaring
StateDirectory so systemd gives the dynamic user real persistent storage.

--name (used as pct/qm create's --hostname/--name) defaulted to
$flake_target (e.g. "lxc-nix-cache"), not $host (e.g. "nix-cache"). Since
proxmoxLXC.manageHostName pulls the guest's real networking.hostName
straight from Proxmox's own container config, this silently overrode
host.nix's hostName with a build-type-specific name. Default --name to
--host instead, so the guest's identity matches host.nix regardless of
which platform variant built it.
Found by spinning up a fresh lxc-nix-cache test container and noticing its
hostname was "lxc-nix-cache" instead of "nix-cache".

New build type dedicated to Tailscale exit-node capability, wired up for
linode/proxmox/lxc like every other build type (the lxc variant is the one
actually intended for deployment). Kept separate from the "server" host
rather than bundling exit-node capability onto it.
Trimmed modules/tailscale/exit-node.nix down to pure exit-node behavior:
dropped the old --advertise-routes=${vars.lanCidr} bundling (meaningless
for a Linode-hosted VPS with no path to the LAN), and switched
extraUpFlags -> extraSetFlags. Confirmed against nixpkgs' tailscale.nix
that extraUpFlags is only applied by tailscaled-autoconnect, which itself
only runs when services.tailscale.authKeyFile is set -- nothing in this
repo sets one, so the old flags would never have actually been applied.
extraSetFlags runs unconditionally via tailscaled-set on every boot, so
--advertise-exit-node self-reapplies once the operator has done the
one-time manual `tailscale up` auth.
Verified: all three new targets eval cleanly, nixpkgs-fmt/statix clean,
and a dry-run build of lxc-tailscale-exit-node's tarball resolves its full
closure including tailscaled-set.service.

virtualisation/proxmox-lxc.nix registers the Nix store DB via a systemd
service, never an activation script -- so neededForUsers sops secrets
(password hashes) and the user-creation step that consumes them never ran
on a real first boot, leaving /etc/shadow stuck with build-time placeholder
entries. boot.postBootCommands looked like the right hook (stage-2-init.sh
does invoke it) but switch-to-configuration behaves unreliably that early,
before systemd itself is up. Fixed with a genuine oneshot systemd service,
gated by ConditionPathExists so it only ever runs once.
Confirmed live via a from-scratch destroy+rebuild+redeploy of the
lxc-nix-cache test container: real password hashes applied automatically,
systemctl is-system-running -> running, zero failed units.

The real root cause behind the original nix-cache 502, traced all the way
through: modules/installer/host-keys.nix (which NIXOS_HOST_KEYS_DIR=...
--impure actually wires up) is only ever imported by the installer's own
modules/installer/common.nix -- modules/platforms/lxc.nix, which every
real lxc-* host build actually uses, never imported anything like it.
docs/auto-installer.md previously claimed NIXOS_HOST_KEYS_DIR bakes a key
into lxc-* tarballs "the same way it does for the ISO/PXE installer
images" -- that was never actually true; I wrote it without verifying the
mechanism existed for lxc.nix specifically.
In practice this meant every lxc-* container booted with a freshly
self-generated SSH host key that could never match whatever .sops.yaml
actually trusts for that target, so *every* secret -- not just
cache-priv-key -- silently failed to decrypt. No error surfaces in the
boot log for this: the activation step that installs secrets only runs
on a genuinely fresh first activation and silently no-ops once
/run/current-system already exists, so by the time anyone looks the
window has closed. Found by manually invoking sops-install-secrets
directly: "Error getting data key: 0 successful groups required, got 0".
Fixed by giving modules/platforms/lxc.nix the same key-baking mechanism
the installer has, but keyed to its own exact flake target and placing
the key directly at /etc/ssh/ssh_host_ed25519_key (no copy step to stage
for, unlike the installer's /etc/host-keys/ staging area -- an lxc-*
tarball has no install step). The target name comes in via
specialArgs.flakeTarget (new, set by flake.nix's mkTarget) rather than
being read back from config.environment.etc."flake-target" -- reading
that back from within a module that also contributes to
environment.etc is circular (confirmed: "infinite recursion
encountered").
Verified live end-to-end against the real test container (lxc-nix-cache,
VMID 100 on pve.sweet.home): destroyed it, rebuilt the tarball fresh with
the fix, recreated it, and confirmed /run/secrets/ now has all three
secrets this host needs (beszel-token, cache-priv-key, nix-github-token),
nix-serve is active (running), and curl http://localhost/nix-cache-info
succeeds both directly and through nginx.

exit-node.nix advertised --advertise-exit-node/--advertise-routes but
never enabled IP forwarding, so it wouldn't actually route traffic.
services.tailscale.useRoutingFeatures = "server" is the built-in way to
get the sysctls right without duplicating modules/networking/enable-ip-forwarding.nix.
Also opens the firewall for direct (non-DERP-relayed) peer connections,
and now imports enable-service.nix instead of duplicating `enable = true`,
so "plain tailscale" and "tailscale exit node" are two composable modules.

Found and fixed live against a real test container (VMID 100, lxc-nix-cache
on pve.sweet.home) after the previous pct-restore-to-pct-create fix still
produced a container that booted into garbled console output:
1. pct create's own CLI default for --unprivileged is privileged (unlike
the web UI, whose checkbox defaults the other way), but
modules/platforms/lxc.nix sets proxmoxLXC.privileged = false, so the
image assumes it's running unprivileged. Real mismatch -- now passes
--unprivileged 1 explicitly.
2. The actual root cause of the garbled console: modern (v247+) systemd
routinely uses nested user namespaces and credential mounts (even
plain getty units, via LoadCredential=-style mechanisms), which
AppArmor's default LXC confinement denies without --features
nesting=1,keyctl=1. Confirmed via the host's kernel audit log: every
getty unit was crash-looping on a denied /run/credentials/* mount
every ~3s, and core services like nsncd failed userns_create the same
way -- the system never finished activating. Fixed live (pct set +
restart on the running test container) before committing the script
change: systemctl is-system-running went from never completing to
"running" with zero failed units.
3. --memory doesn't touch swap -- confirmed live it silently stayed at
Proxmox's own 512M default with --memory 2048. Now defaults --swap to
whatever --memory resolves to.
docs/auto-installer.md's manual pct create walkthrough gets the same
fixes, with the "why" for each flag, since a human following it by hand
would hit the identical bugs.

Two independent problems found while actually running the script:
1. nix build/nix-shell retry each unreachable substituter/builder up to
5x with backoff, per store path -- with nix-cache down this compounds
into minutes of noise. scripts/env.sh gains nix_extra_opts(), which
probes http://nix-cache and nixremote@nix-cache:22 once via plain
curl/TCP (bypassing Nix's own retry logic entirely -- confirmed
nix store ping still retries 5x even with a short connect-timeout)
and exports the decision so create-proxmox-resource.sh and the
sync-host-keys.sh subprocess it shells out to both reuse it instead
of probing independently.
2. The actual failure: "archive contains no configuration file". pct
restore expects a vzdump backup archive with embedded config;
config.system.build.tarball is a plain CT template tarball -- wrong
Proxmox mechanism entirely. Fixed to pct create against it as a vztmpl
template instead, uploaded to /var/lib/vz/template/cache/ rather than
/var/lib/vz/dump/. This same wrong claim had propagated into
docs/auto-installer.md, README.md, and CLAUDE.md from when the script
was first written -- corrected everywhere.
Also: checks for an already-uploaded image on the node (fixed
<flake_target>.tar.xz/.raw naming) before building, skipping build+upload
entirely if found (--force-rebuild to always rebuild).

sync-host-keys.sh: generates/registers SSH host keys and their
.sops.yaml/secrets/*.yaml recipients for flake targets, idempotently.
--all, <target>, --remove, --regenerate-all-keys, all with --dry-run
(verified zero-side-effect via a sandboxed git-status check across every
mode). Only ever touches anchors with a corresponding host-keys/ file --
&admin and any hand-registered real-host anchor are never listed,
removed, or regenerated. Supersedes running prepare-host-key.sh one host
at a time for any target that already has a flake entry.
create-proxmox-resource.sh: builds a lxc-*/proxmox-* target's
tarball/disk image and creates it on a real Proxmox node, or reconfigures
an existing resource's cores/memory/disk (--modify, always requires
typing the VMID back to confirm). Refuses to create a new resource for a
VMID that already exists, and refuses to duplicate a host identity that
already has a real deployment elsewhere (variables.nix's new
deployedTargets, checked by hostName so it also catches cross-platform
duplicates) unless --allow-duplicate-host is passed. --dry-run throughout.
scripts/env.sh centralizes the Proxmox connection config both scripts
(and future ones) share. Also fixes an unrelated gap found along the way:
proxmox-* Disko image builds write their .raw file straight into the
repo root, and .gitignore never covered it.

nix-serve's secretKeyFile was a manual, undocumented-outside-a-comment
`nix-store --generate-binary-cache-key` step per host -- easy to miss on
a fresh nix-cache instance (as lxc-nix-cache testing just found: systemd
fails the unit with EXIT_CREDENTIALS when LoadCredential can't find the
source file, which nginx then reports as a 502 from clients). It also
can't be regenerated per-host safely: modules/nix-cache/client.nix
hardcodes every client's trust in one specific public key, so every
nix-cache instance has to share the exact same keypair.
Sourced from secrets/nix-cache.yaml's new cache-priv-key entry instead,
via the same sops-nix pattern every other secret in this repo already
uses. Verified the added value derives to the exact public key
modules/nix-cache/client.nix already trusts before committing.

Adds nested vars.nfsShares (subpath + mountpoint per dataset, previously
duplicated independently across server.nix's NFS exports, mount-data.nix's
client mounts, docker.nix's tmpfiles rules, traefik's log rotation path,
and hosts/server/host.nix's beszel config), vars.ports (every literal port
in modules/ and hosts/, kept as separate entries per service even where
numbers coincide so changing one can't silently change another), plus
vars.proxmoxImageSize, vars.nixCacheGcMaxAge, vars.traefikLogRotate, and
raspberryPiHost/raspiNfsPath/raspiMountpoint for the Pi's own NFS export.
Also fixes docker.nix/minimal.nix/gui.nix hardcoding the literal "nixos"
username instead of the existing vars.primaryUser, found during the sweep.
system.stateVersion is deliberately left untouched everywhere -- per
NixOS's own docs that value must stay fixed from first install, not
follow any shared variable.

flake.nix's nixpkgs.url/home-manager.url can't source a version string
from variables.nix -- flake input resolution requires a plain string
literal, confirmed empirically (nix flake metadata errors with
"expected a string or a path but got a thunk" otherwise). This script
is the one-command alternative: bump both release branches in flake.nix
via targeted substitution (never a blind repo-wide replace, so it can't
collide with stateVersion strings elsewhere), with an upstream branch
existence check before writing, plus an optional --tooling flag for
codex-maintenance.sh's separately-pinned nixpkgs-fmt/statix fetch.

Linode provisions and sizes /dev/sda (root) and /dev/sdb (swap) itself
as whole, unpartitioned block devices before the OS ever boots.
modules/disko/linode.nix declares them with destroy = false (skips
Disko's wipe stage for these disks entirely) and a bare filesystem/swap
content type matching that existing layout, so re-running it against an
already-provisioned disk only mkfs/mkswaps if blkid shows it isn't
formatted yet -- never repartitions or destroys data.
With every host reachable through the installer menu now carrying a
Disko config, auto-install.sh no longer needs to probe the flake and
branch between `disko --mode destroy,format,mount` and a bind-mount
fallback -- it just always runs Disko.

Both existed only so the installer could boot as an LXC container and
nixos-install some other host from within it, but lxc-* targets are
already excluded from the install menu (nixos-install can't touch its
own running root filesystem), and now have their own direct tarball
path anyway. That left the installer's own LXC form with no real use
case, and packages.all with only two members worth bundling.

Both check-nixos.yml workflows (GitHub + Gitea) now call
scripts/codex-maintenance.sh instead of a hand-rolled eval-only loop,
closing a real gap: CI previously enforced none of the secret grep,
nixpkgs-fmt, or statix checks that codex-maintenance.sh already runs
locally — nothing was stopping that from regressing. One script now
backs both, instead of two copies that can drift from each other.
codex-maintenance.sh itself is extended to cover buildable surface
that wasn't validated anywhere before: packages.x86_64-linux.*, plus
config.system.build.tarball (lxc-* hosts) and
config.system.build.diskoImagesScript (proxmox-*, excluding the
installer's own proxmox-lxc target, which has no disko config).
Also:
- scripts/prepare-host-key.sh: dropped the redundant
[path-to-nixos-repo] parameter — it always defaults to the repo the
script itself lives in now, so a second argument never made sense
after the nix-auto-installer migration.
- Removed prepare.sh (dead pre-disko manual parted/mkfs/mkswap
partitioning, fully superseded) and
scripts/create-linode-installer-disk.sh (incomplete draft for an
abandoned dd-via-rescue-mode approach; Linode hosts already deploy
fine through the normal auto-installer flow).
- docs/pxe-boot.md: fixed a stale `nixosConfigurations.pxe-boot` eval
command (pre-refactor flat name, not a real flake attribute
anymore) and added a cross-reference to docs/auto-installer.md.
- CLAUDE.md/README.md: full documentation pass reconciling this
session's changes — modules/installer/, modules/pxe-boot/, the
LXC/Proxmox image-building deployment paths, corrected the
password-hash/SSH-key locations in the safety-rules section (both
had drifted to reference files/paths that no longer exist), and
added session-workflow guidance to prefer targeted host evals over
full-repo sweeps for incremental changes (explicitly scoped to
interactive sessions, not CI).

modules/disko/proxmox.nix gains imageSize (20G default) and a
per-host imageName (networking.hostName, so every proxmox-* host
produces a distinctly named image instead of an identical main.raw).
This is the same disko.devices config already used to format a real
disk on install, so it's available for every proxmox-* target with no
per-host changes needed:
nix build .#nixosConfigurations.<host>.config.system.build.diskoImagesScript
sudo ./result --build-memory 2048
docs/proxmox-images.md covers building, host-key pre-seeding via
disko's --pre-format-files (same host-keys/ workflow as the installer
and LXC tarball paths), and the qm import/attach sequence for
deploying the result to Proxmox.
Also fixes a real bug in auto-install.sh found while testing: the
disko confirmation bypass used --yes, which disko's CLI doesn't
recognize at all (the actual flag is --yes-wipe-all-disks) — so the
"skip confirmation" flag was silently a no-op and the interactive
prompt kept appearing regardless.

LXC hosts (device busy fix):
modules/platforms/lxc.nix now imports nixpkgs' own
virtualisation/proxmox-lxc.nix, giving every lxc-* host a real
config.system.build.tarball output — a directly `pct restore`-able
Proxmox container image. This is the actual bug fix behind the
"cannot remove real root directory: device busy or in use" error:
lxc-* targets were only reachable through nixos-install, which
bind-mounts / onto /mnt for containers (no raw disk to partition)
and then correctly refuses to modify the filesystem it's currently
running on. auto-install.sh's menu now excludes lxc-* targets
entirely (they deploy via nix build + pct restore instead, see
docs/auto-installer.md) — and, on the same reasoning, also excludes
`installer`/`proxmox-lxc`, which are the installer image's own flake
targets, not deployable hosts.
manageHostName = true keeps host.nix's declared hostnames (upstream's
default would let Proxmox's ambient container config win instead);
privileged = false matches how these containers are actually created.
Eval warnings, now zero across all 19 nixosConfigurations + 4 packages:
- Multiple password options (root/nixos in the installer): nixpkgs'
own installer profile sets initialHashedPassword = "" for
passwordless login, conflicting with our explicit hashedPassword.
Force-nulled the upstream option rather than adopting passwordless
login, since this image now also boots over LAN PXE with
PasswordAuthentication enabled.
- boot.zfs.forceImportRoot default value: set explicitly to false
(matching the two places that already did) in
modules/common/configuration.nix and modules/installer/common.nix,
covering every host and the installer alike.
- Deprecated pkgs.system in modules/build-types/gui.nix: switched to
pkgs.stdenv.hostPlatform.system.
All confirmed non-behavioral where it matters: unrelated hosts'
drvPaths are byte-identical to their pre-existing baselines throughout.

Finishes the nix-auto-installer migration: scripts/prepare-host-key.sh
and the local host-keys/ directory (gitignored, private key material,
never committed — moved as plain files, not through git history)
weren't carried over in the initial migration.
Also implements automatic key staging, replacing the manual
scp-after-boot step:
- modules/installer/host-keys.nix reads host-keys/ via
builtins.getEnv, which Nix silently returns as "" under normal
(non---impure) evaluation — the module is a no-op by default, safe
for CI, until explicitly opted into:
NIXOS_HOST_KEYS_DIR=$(pwd)/host-keys nix build .#iso --impure
When built this way every key present gets baked into the image at
/etc/host-keys/, and auto-install.sh installs whichever one matches
the flake target selected at install time — no manual per-host scp.
- This deliberately includes the PXE netboot variant, even though
pxe-boot serves it unauthenticated over LAN HTTP: accepted
explicitly as a reasonable trade-off for a network that sits behind
LAN-only infrastructure, not the open internet. auto-install.sh
still falls back to /root/host-keys (manual scp) if a key isn't
baked in, so images built without --impure keep working exactly as
before.
- docs/auto-installer.md replaces nix-auto-installer's README,
updated for in-repo paths and the new build flow.
Verified: normal `nix eval` (no --impure) evaluates identically across
all 19 nixosConfigurations + 4 packages with zero host-keys/* entries
(CI-unaffected); with --impure + the env var set, all three installer
variants (installer/ISO, proxmox-lxc, pxe) correctly embed every key
in host-keys/.

Zero W20 (repeated attribute keys), W10 (empty { ... }: variadic
pattern, use _: instead), and W04 (a = x.a instead of inherit)
warnings remain anywhere in the tree, and nixpkgs-fmt --check is
clean on all 46 .nix files.
Repeated-key merges go as deep as statix actually flags per file
(e.g. boot.loader.* nested under boot.loader = { ... } once the
outer boot.* merge exposed it as its own repeat) — every merge is a
pure attribute-path restructuring with no value changes, verified by
comparing config.system.build.toplevel.drvPath before/after for a
representative host per changed module plus a full 19-host + 4-package
eval sweep.
One indentation slip caught and fixed during this pass: nesting
modules/installer/common.nix's environment.etc."auto-install.sh".text
under an environment = { ... } block initially normalized the
script's shebang/set line indentation, which actually changes the
rendered file (Nix's '' string dedent treats it as real content, not
cosmetic whitespace) — reproduced the original's exact indentation
and reverified the rendered script is byte-identical to before.
modules/services/zfs/auto-mount-volumes.nix picked up formatting too;
worth noting it isn't imported by anything in this flake at all.

Folds the separate nix-auto-installer repo's build outputs into this
flake so it can build every auto-installer artifact it used to,
negating the need for that repo:
- modules/installer/{common,iso,proxmox-lxc}.nix — migrated from
nix-auto-installer's common.nix/installer.nix/proxmox-lxc.nix.
- flake.nix gains nixosConfigurations.{installer,proxmox-lxc} and
packages.x86_64-linux.{iso,lxc,pxe,all}, matching the original
repo's interface (nix build .#iso / .#lxc / .#pxe / .#all).
- Dropped the live Gitea PAT baked into every installer image via
environment.etc."git-credentials" — gitea.lan.ddnsgeek.com/beatzaplenty/nixos.git
allows anonymous read, so the installer (which only ever reads the
flake, never pushes) doesn't need a credential at all.
- installer_old.nix wasn't migrated — dead code, unreferenced by the
source repo's flake.nix, and carried a second stale leaked token.
- The installer environment's own hardcoded login password hash is
preserved as-is: sops-nix has no stable per-boot host key to derive
an age key from on ephemeral installer media, so it can't reuse the
same per-host secret mechanism the rest of this repo uses without
separate design work.
- vars.adminSshKey / vars.dockerHost-style dedup: the installer's SSH
authorized key and its FLAKE_BASE_URL domain were exact duplicates
of values already in variables.nix / modules/common/configuration.nix,
so both now reference the single source of truth instead.
Verified eval-equivalent for every existing host (drvPath-identical)
and confirmed the migrated auto-install.sh script renders byte-for-byte
identical to the source repo's output.

directory per concern (tailscale/, beszel/, docker/, nix-cache/):

- enable-ip-forwarding.nix -> networking/
- rotate-traefik-logs.nix -> traefik/rotate-logs.nix
- services/docker-health-to-gotify.nix and services/nextcloud-cron-job.nix
