- ha-server.nix: add xfsprogs to systemPackages so mkfs.xfs is on PATH for
root (needed by cluster-init.sh during initial setup)
- cluster-config.nix: create /var/lib/drbd via tmpfiles to silence
lk_bdev_save warnings from drbd-utils
- cluster-init.sh: dynamically find xfsprogs in /nix/store if not on PATH
(fallback for running VMs before xfsprogs is in the system profile)
- cluster-init.sh: fix DRBD metadata check on node2 — broken regex now uses
grep -E for ERE alternation to correctly skip create-md when DRBD is already
set up (previous regex would have triggered create-md on a live secondary)

Documentation fixes:
- README/AGENTS: rename tailscale-exit-node → tailscale-router, add ha-server
build type and proxmox-ha-server-{1,2} host table rows, add baremetal to
platform list, remove references to non-existent flake-target-refactor-spec.md
and remove-sensetive-info-refactor.md
- docs/auto-installer.md: fix lxc-tailscale-exit-node → lxc-tailscale-router,
add pxe-minimal to the flake outputs list
- variables.nix: fix domainControllerIp comment — IPA is the authoritative DNS
at .253 (Pi-hole is gone), not a forwarding intermediary
Code deduplication:
- Extract duplicate SSH host-key preservation activation scripts from
modules/platforms/lxc.nix and modules/platforms/proxmox.nix into a shared
modules/common/preserve-ssh-host-key.nix; both platforms now import it
- Replace 8-line hand-enumerated NFS export lists in server.nix and ha-server.nix
with a mkNfsExports helper that generates exports from vars.nfsShares — adding
a share to variables.nix now propagates to both exporters automatically
Dead code removal:
- modules/common/configuration.nix: remove leftover NixOS skeleton comments
(hardware-configuration import, grub lines) that were never used
- modules/docker/enable-service.nix: remove commented-out listenOptions and
daemon.settings blocks
- hosts/server/host.nix, hosts/nix-cache/host.nix: remove #DOCKER_HOST comments

Create an IPA group "docker-access" (GID 50010) and pin the local
"docker" group to that GID on all Docker hosts. Any IPA user in the
docker-access group automatically gains docker socket access through
SSSD supplementary-group resolution — no per-host docker.members
entry needed.
Specific changes:
- variables.nix: add dockerAccessGid = 50010
- modules/docker/enable-service.nix: lib.mkForce docker GID to
dockerAccessGid, removing the need to name individual IPA users
- modules/build-types/docker.nix: remove direct wayne docker.members
entry (access now comes from IPA group)
- modules/ipa/client.nix: refactor repeated security.* / systemd.*
top-level keys into merged attribute sets (fixes statix W20); add
security.pam.services.lightdm.makeHomeDir so the GUI login path
also creates the home dir on first login

zpool create -f was called if `zpool import -d /dev/disk/by-id` failed,
which could happen due to a race with systemd-udev-settle. The disk
would then be visible by the time zpool create ran, silently destroying
all data on an otherwise-intact pool.
Fix: locate the data disk first, retry the import directly against it
as a fallback, then check zdb -l for existing ZFS label metadata before
concluding the disk is blank. Remove -f so zpool create refuses rather
than overwrites if a pool is present.

FreeIPA (the new authoritative DNS) cannot reach 100.100.100.100
(Tailscale's internal MagicDNS resolver) directly because the DC is not
a Tailscale node. The tailscale-router IS a Tailscale node and can
reach 100.100.100.100 via tailscale0, so it now runs a dnsmasq
instance on its LAN interface that forwards all ts.net queries to
Tailscale's resolver.
After deploying this host, configure FreeIPA with:
kinit admin
ipa dnsforwardzone-add ts.net \
--forwarder=192.168.2.222 \
--forward-policy=only
This replaces Pi-hole's conditional forwarder for ts.net and restores
resolution of Tailscale MagicDNS names (e.g. raspberrypi.tail13f623.ts.net)
for all LAN hosts using FreeIPA as their DNS server.

Adds static IP configuration to every NixOS host in the flake that
has a fixed LAN address, and centralises all network primitives
(IPs, gateway, prefix length, interface names) in variables.nix so
there is one place to update if any of them change.
variables.nix additions:
- lanGateway / lanPrefixLength — LAN gateway and /24 prefix, replacing
every hardcoded 192.168.2.254 / 24 across host files
- lxcLanInterface / vmLanInterface / vmStorageInterface — NIC names for
LXC containers (eth0), Proxmox VMs (ens18), and the HA storage NIC
(ens19), used as attribute keys so changing the name is a one-line edit
- haStoragePrefixLength — /29 for the storage subnet, mirrors haStorageCidr
- Per-host IP variables: nixCacheIp (.224), tailscaleRouterIp (.222),
torRelayIp (.221), serverIp (.226), dockerIp (.225)
host.nix changes:
- tailscale-router, tor-relay, nix-cache, pxe-boot: useDHCP = false,
static address on eth0 (lxcLanInterface), struct-form defaultGateway
(required when using systemd-networkd which LXC containers use)
- server, docker: useDHCP = false, static address on ens18 (vmLanInterface),
struct-form defaultGateway (works for both scripted networking and networkd)
- ha-server-1, ha-server-2: replace hardcoded 192.168.2.254 / 24 / 29
with the new variables; no functional change for these hosts
modules/build-types/pxe-boot.nix:
- Domain-controller kickstart template: replace hardcoded 192.168.2.138
and 192.168.2.254 with vars.domainControllerIp / vars.lanGateway /
vars.lanPrefixLength / vars.homeDomain so the template stays correct
if the DC IP or domain is ever changed again

dnsmasq binds port 53 by default even when only proxy DHCP is needed.
systemd-resolved already owns port 53 on the pxe-boot container, so
dnsmasq crashes at startup. Setting port=0 disables the DNS listener
entirely — pxe-boot only needs the proxy DHCP path for iPXE chainloading.

dnsmasq config was placed inside systemd.services{} block, making Nix

haServer1/2Host, haServer1/2Ip, haServerVip, haStorageRoot, haIscsiIqn
ports.haServerDrbd/Iscsi/Corosync{1,2,Crypto}/PacemakerRemoted/Pcsd
scripts/ha/ (migrated + updated from test-lab/ha/)
cluster-init.sh — generates corosync authkey, initialises DRBD/XFS/iSCSI,

cluster-enable-stonith.sh — enables fence_pve_ssh STONITH after key deploy
fence-pve-ssh.py — Proxmox SSH fence agent (node names updated to ha-server-1/2)

Adds an unattended install option to the PXE boot menu that installs
Rocky Linux 9 and configures FreeIPA on the domain-controller.sweet.home
host without any operator interaction after selecting the menu entry.
How it works:
- fetch-rocky-pxeboot.service downloads the Rocky 9 Anaconda pxeboot
kernel and initrd from the Rocky mirror on first pxe-boot deploy
(idempotent, same pattern as fetch-debian-netboot)
- rocky-freeipa.ipxe boots Anaconda with inst.ks pointing at the
hosted Kickstart and net.ifnames=0 biosdevname=0 for stable eth0
- rocky-freeipa.ks (generated, includes vars.adminSshKey) performs:
- Minimal Rocky 9 install with ipa-server + ipa-server-dns
- Static IP 192.168.2.138 via NM connection file written in %post
- /etc/hosts fixed for FreeIPA FQDN requirement
- Random DM + admin passwords generated and saved to
/root/ipa-credentials.txt (chmod 600, never hardcoded)
- freeipa-first-boot.service oneshot enabled to run
ipa-server-install on the first real boot (~20 min)

showmount and the NFSv3 mount protocol need mountd reachable after querying
portmapper on 111; the server was only opening TCP 111 and 2049, causing
clients (e.g. Proxmox GUI NFS storage scan) to time out connecting to
mountd on 20048. Also adds UDP for all three ports — portmapper, nfsd, and
mountd all use both protocols.

Adds modules/pxe-boot/mount-pxe-images.nix, which mounts
server.sweet.home:/tank/proxmox/pxe-images at /mnt/pxe-images via NFSv4.2
(x-systemd.automount on Proxmox VMs, nofail on LXC containers — same pattern
as docker/mount-data.nix). The pxe-boot build-type now imports this module and
replaces the previous local /srv/pxe/http/images directory rule with an L+
symlink pointing to /mnt/pxe-images, so large images (ISOs, disk images) live
on the NFS share rather than the host's own root disk.

Adds a `fetch-debian-netboot.service` oneshot that downloads the Debian
bookworm netboot kernel and initrd from deb.debian.org on first boot,
stages them under /srv/pxe/http/debian/, and serves them via a generated
debian.ipxe chain script. The service is idempotent — it skips the
download if both files are already present.
Also merges the previously split systemd.tmpfiles.rules and
systemd.services blocks into a single systemd = { ... } attrset to
satisfy statix's repeated-keys lint.

(all three platform variants as recipients). The secrets file must be
created manually before deploying — see instructions in PR.

extraCommands runs after nixos-nat-post is deleted but before it is
re-created, so -A nixos-nat-post silently fails every time. POSTROUTING
is a built-in chain that always exists; target it directly instead.
The -C idempotency check prevents duplicate rules on firewall reloads.
Drop networking.nat.enable -- it was only needed for the sub-chain that
turned out to be the wrong target.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
networking.nat.externalInterface without internalInterfaces creates the
nixos-nat-post chain but inserts no MASQUERADE rule into it — confirmed
by inspecting the live firewall-start script on the deployed host.
Add the rule explicitly via firewall.extraCommands targeting nixos-nat-post,
scoped to LAN source traffic (vars.lanCidr) going out tailscale0.
extraStopCommands removes it on firewall stop.

Without SNAT on tailscale0, Tailscale drops forwarded packets from LAN
source IPs (192.168.2.x) because they are not recognised Tailscale
addresses. With networking.nat.externalInterface = "tailscale0", all
traffic leaving through the Tailscale tunnel is masqueraded to the
router's own Tailscale IP (100.x.x.x), making it indistinguishable from
locally-originated traffic. Conntrack handles the return path.

Complete the rename so all identifiers match networking.hostName:
- flake.nix: attribute names and buildType strings
(linode/proxmox/lxc-tailscale-subnet-router → *-tailscale-router)
- modules/build-types/tailscale-subnet-router.nix → tailscale-router.nix
- .sops.yaml: anchor and alias names (age keys unchanged, no re-encrypt needed)
- host-keys/: local gitignored key files renamed (not committed)

The host was always intended as a LAN subnet router (--advertise-routes),
not a full exit node (--advertise-exit-node). Rename every trace of
"exit-node" to "subnet-router" and remove the --advertise-exit-node flag
from extraSetFlags; the operator supplies --advertise-routes at first
tailscale up and Tailscale persists it in state across reboots.
Routing sysctls (useRoutingFeatures = "server"), openFirewall, and
trustedInterfaces = ["tailscale0"] are still required for subnet routing
to work, so the module is kept — just correctly named.

zfs-import-tank.service spun 60 s then failed with no pool found.
Add zfs-init-tank.service that runs before the import: exits immediately

virtio-scsi naming for the second disk) with all required NFS datasets

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.
New tor-relay build type (currently lxc-only) running a plain Tor
middle relay via modules/tor/enable-relay.nix, plus nyx for

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.

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.

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.

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

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,

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.

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.

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.
