Any enrolled host now automatically gets a Home Manager profile for the
IPA primary user (vars.ipaUser = "wayne"), covering what IPA doesn't:
dotfiles, user-scoped packages (tmux, sshfs), and EDITOR variable.
The home directory is pre-created by systemd-tmpfiles so HM activation
succeeds on steady-state systems before first login; pam_mkhomedir remains
as a fallback for fresh deploys where SSSD hasn't cached the user yet.
A minimal users.users stub satisfies NixOS's assertion requirements
(isNormalUser + group) that arise because home-manager.useUserPackages
creates a users.users entry to install packages to /etc/profiles/per-user/.
The stub is shadowed by SSSD at runtime (security.ipa sets passwd: sss files).

ipa-getkeytab confirmed ipa.sweet.home doesn't respond to LDAP;
domain-controller.sweet.home is the actual IPA server FQDN.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds modules/ipa/client.nix — a parameterized module that joins a NixOS host
to the sweet.home FreeIPA domain without ipa-client-install. It configures
security.ipa (SSSD, Kerberos, PAM, NSSwitch) and places a pre-provisioned host
keytab via sops-nix binary secret so enrollment is fully reproducible from the
flake.
- variables.nix: adds ipaServer (FQDN of the FreeIPA KDC; security.ipa.server
requires a hostname, not an IP, for Kerberos/TLS)
- certs/ipa-ca.crt: placeholder for the IPA CA public certificate (operator
replaces with: curl http://<ipa-server>/ipa/config/ca.crt)
- secrets/nix-cache.keytab: placeholder binary sops file (operator replaces
with the encrypted keytab after ipa host-add + ipa-getkeytab)
- .sops.yaml: adds creation rule for secrets/nix-cache.keytab (same recipients
as secrets/nix-cache.yaml)
- hosts/nix-cache/host.nix: imports the IPA client module; adds
networking.domain so the host's FQDN resolves correctly
Module header documents the three operator steps needed per host before deploy.

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

Adds proxmox-ha-server-1 and proxmox-ha-server-2 as real mkTarget entries
alongside the existing proxmox-server, backed by a new ha-server build type.
New modules
modules/ha/cluster-config.nix — DRBD resource + corosync nodelist sourced
from vars (haServer1Host/Ip, haServer2Host/Ip); resource-only fencing for
production STONITH; HA port firewall rules for DRBD, iSCSI, Corosync, pcsd
modules/build-types/ha-server.nix — imports pacemaker-stack + iscsi-target
+ cluster-config + beszel; NFS exports from vars.haStorageRoot (XFS-over-DRBD
mount); nfs-server.service.wantedBy force-cleared so Pacemaker controls
start/stop on the Active node only
New hosts
hosts/ha-server-{1,2}/host.nix — static IP from vars, unique hostId; sops
secrets (beszel, corosync authkey) are TODOs pending sync-host-keys.sh
variables.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,
creates NFS dataset dirs, configures Pacemaker with DRBD + XFS + iSCSI
+ nfs-server + VIP; STONITH disabled initially (enable separately)
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)
acceptance-tests.sh — T1–T7 production acceptance tests
test-lab/ha/ removed — all Nix config moved to modules/ha/ and
modules/build-types/; scripts moved to scripts/ha/

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.

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.
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.
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.

variables.nix's deployedTargets was a manually-maintained list with no
enforcement keeping it in sync with reality -- it caused two separate
false refusals in a row (naming a VM as deployed well after it had been
destroyed, then matching a target against itself once the list was
"corrected"). Static files can't track whether a resource still actually
exists.
create-proxmox-resource.sh's duplicate-host guard now queries the
Proxmox node directly (qm/pct's own name/hostname config, matched
against --host) instead. Also fixes a gap in that live check: it
originally swallowed ssh failures and would have silently treated "can't
reach the node" the same as "checked, nothing there" -- it now refuses
instead of guessing when the node can't be reached.
deployedTargets is removed entirely from variables.nix since nothing
else in the repo consumed it once this script no longer does; README.md's
Hosts table remains the sole source of truth for "(real, deployed)"
status. CLAUDE.md and the script's own --help/comments updated to match.

The old proxmox-nix-cache VM was destroyed and nix-cache is being
redeployed as an LXC container going forward. Without this update,
create-proxmox-resource.sh's duplicate-host check (which only reads this
static list, not live Proxmox state) kept refusing to create
lxc-nix-cache even though nothing named nix-cache actually exists on the
node anymore.

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.

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.

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.

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.

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
named nix-minimal regardless of which platform it runs on.

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.
