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/.

Adds debian@surface's existing SSH key (already used as its admin
key elsewhere in this repo) to vars.remoteBuilderAuthorizedKeys so
nix-cache will accept it as a distributed-build client once deployed.

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.

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.

Remove the nonexistent kuma host and add the missing linode-minimal
host across README, AGENTS.md, docs, and CI eval workflows so they
match flake.nix's nixosConfigurations. Also add CLAUDE.md with
architecture/safety guidance for future Claude Code sessions.
