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.

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.

Pulls the beszel hub / PVE / PBS ports, the docker-compose host's LAN
name, and the remote-builder client SSH keys out of scattered inline
literals across modules/hosts and into variables.nix as the single
source of truth, matching the existing pattern for other cross-host
references (nixCacheHost, nfsServerHost).

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.

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.
