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).

Adds the proxmox-minimal host's age key (derived from its SSH host

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.

CLAUDE.md's "Composition pattern" section still described the
pre-refactor layout (hosts/<host>/configuration.nix as a thin imports
list, hardware-configuration wired in from flake.nix) from before the
platform x build-type matrix landed. Rewrite it to match the current
mkTarget/host.nix architecture and the module moves from the prior
commit. Also fixes docs/nix-cache.md, which referenced a
modules/nix/ path that never existed in this repo.

Several single-purpose modules sat at modules/ root or in the
services/ catch-all despite the repo's established pattern of one
directory per concern (tailscale/, beszel/, docker/, nix-cache/):
- remote-builder-client.nix -> nix-cache/ (always co-included with
nix-cache/client.nix in flake.nix's mkTarget, same buildType guard)
- set-locale.nix -> common/ (unconditionally imported by
common/configuration.nix already)
- 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
-> docker/ (both only ever imported by the docker build type, same
as the rest of modules/docker/*)
Pure path moves plus import-path updates in flake.nix,
common/configuration.nix, and build-types/docker.nix — verified
eval-equivalent (drvPath-identical) across representative hosts.

hosts/server/host.nix and hosts/nix-cache/host.nix each hand-rolled the
same sops secret/template/environmentFile wiring for the beszel agent
token, differing only in the sops file path and template name. Factor
it into modules/beszel/host-token.nix ({ name, sopsFile }) so a third
host can adopt it without copy-pasting the boilerplate again. Also
drops two dead, stale commented-out HUB_URL lines left over from
before variables.nix grew a homeDomain var.

boot.isContainer disables services.udev, which NetworkManager depends on
to enumerate devices — this left NM unable to reliably manage the
container veth, breaking DHCP-hostname registration in Pi-hole. It also
defaulted networking.useHostResolvConf to true, which assumes a
systemd-nspawn-style resolv.conf bind-mount that real Proxmox LXC doesn't
provide (nixpkgs' own proxmox-lxc.nix module forces this false for the
same reason). Also guard the networkmanager extraGroups membership in the
minimal/gui build-types, since that group only exists when NM is enabled.

linode-minimal, proxmox-minimal, and lxc-minimal now all share
hosts/nix-minimal/host.nix instead of three separate per-platform
host files with different hostnames — every minimal-buildtype host is

LXC containers share the host kernel — Proxmox starts them by exec'ing
/sbin/init directly in the container's rootfs, no bootloader or initrd
involved at all. Without boot.loader.initScript.enable, that file
isn't wired to launch the current generation, so even a correctly
installed system (see the nix-auto-installer bind-mount fix, same
underlying issue) could still fail to come up after reboot. This is
exactly what nixpkgs' own virtualisation/proxmox-lxc.nix module sets
for the same reason.

One file (variables.nix) holding every value that was previously
hardcoded and repeated across modules: LAN domain/CIDR, home/tailnet
domains, cross-host references (nix-cache substituter hostname, NFS
server hostname, remote-builder user), PXE/PBS IPs, timezone, and the
primary username.
Wired in via flake.nix's specialArgs (and home-manager's
extraSpecialArgs for the two home.nix files), so any module picks it
up by just adding `vars` to its function arguments — no explicit
import needed. Two hosts (nix-cache, server) now derive their own
networking.hostName from the same variable other hosts use to reach
them, so there's exactly one place to change either identifier.
Purely mechanical: every substituted value matches what was already
there, confirmed by identical toplevel .drv paths for all 17 targets
before and after.

Audited the working tree and full git history for committed secrets
(gitleaks + trufflehog + manual grep, see secrets-inventory.md, kept
local/gitignored per the spec). Found: a password hash shared by root
and the nixos user across every host, two live Beszel monitoring
tokens, and a GitHub fine-grained PAT embedded in a home-manager
nix.conf.
Migrates all of them to sops-nix:
- .sops.yaml + secrets/*.yaml, encrypted for admin + the age keys
derived (via ssh-to-age) from each live host's existing SSH host
key — no new key material transferred to any machine.
- users.users.{root,nixos}.hashedPasswordFile replaces the inline
hashedPassword shared by every target.
- The GitHub PAT moves from a home-manager-managed, store-visible
nix.conf to a sops.templates-rendered file included via nix.conf's
native !include, system-wide instead of per-user.
- Beszel TOKEN moves from `environment` (store-visible) to
`environmentFile` (runtime-only via sops.templates); the dead
commented-out docker token is removed from the tree entirely.
Added a tracked pre-commit hook (gitleaks protect --staged, wired via
core.hooksPath) so a secret can't be committed by accident again, and
documented the sops workflow in README.md.
Structural verification only: all 17 flake targets evaluate, and
`nix build --dry-run --no-link` succeeds for the three currently
deployed hosts. Per CLAUDE.md, actual `nixos-rebuild switch` — the
step that confirms secrets decrypt and services start on a real
machine — is left for manual verification.
Git history still contains the original plaintext secrets; scrubbing
history (Milestone 3) and rotating every credential (Milestone 4) are
separate, deliberately gated steps per remove-sensetive-info-refactor.md.

Generates all nixosConfigurations from mkTarget(platform, buildType,
hostPath) instead of hand-written per-host blocks, so adding a new
platform or build type is a one-line addition. Per-machine identity
(hostname, hostId, secrets, stateVersion) moves into hosts/<name>/host.nix;
platform-specific config (hardware, boot, networking) into
modules/platforms/*.nix; build-type config (minimal/server/docker/gui/
nix-cache/pxe-boot) into modules/build-types/*.nix.
Old flat targets (nixos, docker, server, nix-cache, nix-minimal, pxe-boot)
are replaced by the 17-target <platform>-<buildtype> matrix; each new
target was verified to evaluate before its old counterpart was removed.
CI workflows and docs/aliases now discover hosts dynamically via
nixosConfigurations attrNames and /etc/flake-target instead of hardcoded
lists, so they can't drift from flake.nix again.
