- 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)

Root SSH was failing because only the RSA admin key was authorized but the
local dev box only has an ed25519 key. Fix:
- cluster-config.nix: add ed25519 keys to root (same set as nixos user) so
future deployments work without the temp-key workaround
- deploy.sh/acceptance-tests.sh: SSH as nixos user with sudo instead of root@
- cluster-init.sh: HA_USER/HA_KEY env vars + n2_ssh()/n2_scp() helpers so
inter-node SSH works regardless of whether root-to-root is available
- deploy.sh Phase 6: generate temp keypair, authorize on node2, place on node1
for root to use during cluster-init, clean up afterward

- Add root SSH key + passwordless sudo to ha-server nodes (needed for
deploy script to run cluster-init.sh via SSH as root on node1)
- Fix cluster-init.sh: correct default IPs (228/227/229 per variables.nix),
use \${VAR:-default} for all config so deploy.sh can override via env
- Fix acceptance-tests.sh: same IP corrections, add -i flag to SSH calls,
use \${VAR:-default} pattern
- Fix deploy.sh dry-run bugs: pve_check() always runs SSH for read-only
probes so bridge existence check is accurate; wait_for_ssh skips in
dry-run instead of timing out
- Fix cluster-init invocation: upload script via scp and run via SSH as
root on node1 (was incorrectly trying to run the script locally)
- Fix acceptance-tests invocation: pass IP env vars from deploy.sh

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

Grants the domain wayne account docker socket access on docker.sweet.home
without needing sudo, alongside the existing nixos local user membership.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
On first enrollment /home/wayne doesn't exist until the IPA user's first
login (pam_mkhomedir creates it). home-manager-<user>.service cd's into
the home dir immediately and fails with ENOENT, causing the whole rebuild
activation to return exit code 4.
Add ConditionPathExists so systemd skips the service (condition not met,
no failure) instead. After first login the dir exists and subsequent
rebuilds activate Home Manager normally.

HM's useUserPackages creates a users.users stub for every configured HM
user, which lands wayne in /etc/passwd. NixOS adds pam_sss.so with the
"localusers" flag to the sudo PAM stack when SSSD is enabled; that flag
causes pam_sss to skip SSSD for any user found in local /etc/passwd,
falling through to pam_unix which has no shadow password for the stub.
Result: sudo auth always fails for the IPA user despite being in wheel.
Use NOPASSWD for the IPA user in sudoers instead. The IPA user already
authenticated to reach a shell (SSH key from IPA or Kerberos), so
re-prompting via a broken PAM path is security theater on a homelab.

initgroups() uses NSS (groups: files sss) to build the supplemental
group list at login. Adding wheel to the local users.users stub means
the IPA user gets wheel membership from /etc/group, satisfying sudo's
group check.

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).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
IPA users (e.g. wayne@) don't get Home Manager so the aliases defined in
aliases.nix were invisible to them. Move Switch-nix, Test-nix, and
buildImage into programs.bash in configuration.nix so every user on every
host gets them via /etc/bashrc. Stub out aliases.nix for future per-user
HM-only additions.

The NixOS IPA module adds ConditionPathExists=/etc/krb5.keytab drop-ins
for auth-rpcgss-module.service and rpc-gssd.service via systemd.units.
In LXC containers with keytabs those conditions pass, the services start,
and then fail because auth_rpcgss can't be loaded and rpc_pipefs doesn't
exist in the container namespace.
Use lib.mkForce on our systemd.units text to win the conflict with NixOS's
existing definitions, and include ConditionVirtualization=!container
alongside the ConditionPathExists conditions so the services are skipped
(inactive, not failed) in containers that have a keytab.

modules/ipa/client.nix is now a self-contained NixOS module (no longer a
parameterized function): it checks builtins.pathExists for
secrets/<hostname>.keytab at eval time and enables itself automatically if
found, making it a no-op for hosts without a keytab.
modules/common/configuration.nix imports it so every host in the flake is
a candidate for IPA enrollment — no per-host wiring needed. Adding a
keytab (via scripts/ipa/create-nixos-ipa-host-account.sh) is now the
only step required to enroll a host.
The module also sets networking.domain and networking.nameservers via
mkDefault when active, so new hosts don't need those set explicitly.
Also:
- Remove explicit IPA imports from hosts/nix-cache and hosts/tailscale-router
- Add secrets/pxe-boot.keytab + creation rule; remove incorrect
secrets/nixos.sweet.home.keytab and its creation rule
- Add .sops.yaml creation rules for all remaining host keytabs
(server, docker, tor-relay, nix-minimal, nixos) so the creation script
can target them without manual .sops.yaml edits
- Fix duplicate tailscale-router.keytab rule and corrupted gui.yaml comment
block in .sops.yaml

Script fixes:
- Rename HOSTNAME variable to TARGET (shadowed the bash builtin)
- Fix ipa-getkeytab -s to always use IPA_SERVER, not DC_HOST (diverge if
--dc is overridden to a jump host)
- Remove dead REALM variable
- Add EXIT trap to delete the plaintext keytab if the script aborts before
sops encryption completes; cleared after successful encrypt
- Distinguish real ipa host-add failures from "already exists" instead of
swallowing all errors with || true
- Warn explicitly when no platform age keys exist for the target (keytab
would be admin-only and the host couldn't decrypt it at boot)
- Fix sops fallback from pinned nixos-25.11 channel to nixpkgs (uses the
repo's own flake.lock)
- Expand "next steps" output to include networking.domain and nameservers
lines that host.nix requires for IPA membership
Module docs:
- Point to the script as the primary setup path; move manual steps to a
fallback section
- Note that certs/ipa-ca.crt is already committed (no need to re-fetch)
- Document the networking.domain and nameservers requirements in the header
- Add sync-host-keys.sh as explicit step 0

OpenSSH 10.0 tightened AuthorizedKeysCommand security by checking every
path component of the command binary for group/world-write permission.
/nix/store is 1775 (group-writable by nixbld), so sshd silently skips
the command for any binary in the Nix store — causing IPA pubkey auth to
silently fail with no diagnostic.
Fix: copy sss_ssh_authorizedkeys to /usr/local/bin via systemd tmpfiles
(C+ copies the file rather than symlinking, so the path at runtime is
root-owned/755 throughout), and point AuthorizedKeysCommand at the copy.

NixOS's dnsmasq module defaults resolveLocalQueries to true, which adds
127.0.0.1 to networking.nameservers and binds dnsmasq to listen-address=127.0.0.1.
This made the host route all its own DNS through dnsmasq, which had
no-resolv=true and no upstream for anything outside the tailnet domain —
so every non-tailscale DNS query from the host itself (including SSSD
resolving the IPA server FQDN after the IPA client module was added) failed.
Setting resolveLocalQueries=false limits dnsmasq to its intended role: a
forwarding proxy reachable on the LAN interface for IPA's conditional
forwarder. The host uses domainControllerIp directly (already set in
networking.nameservers in host.nix).

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.

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.

IPA refuses to create a forward zone for ts.net because it's a real

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.

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

production STONITH; HA port firewall rules for DRBD, iSCSI, Corosync, pcsd
modules/build-types/ha-server.nix — imports pacemaker-stack + iscsi-target

mount); nfs-server.service.wantedBy force-cleared so Pacemaker controls
start/stop on the Active node only

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

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)

All 7 acceptance tests pass on live NixOS 25.11 VMs (VMIDs 200/201 on
pve1). Failover completes in ~5 s with data integrity verified.
modules/ha/pacemaker-stack.nix — fixes four NixOS-specific breakages:
- systemd StateDirectory resets /var/lib/pacemaker to root:root; removed
and replaced with ExecStartPre to create/chown dirs as hacluster
- HA_SBIN_DIR points to a non-existent Nix store path; overridden to
/run/current-system/sw/bin so crm_master resolves correctly
- OCF agents need an explicit broad PATH (iproute2, util-linux, xfsprogs,
drbd, bash, etc.) — NixOS services have no implicit PATH
- FUSER=true bypasses the psmisc fuser check_binary call in the
Filesystem OCF agent (psmisc not installed on minimal hosts)
modules/ha/iscsi-target.nix — LIO iSCSI target via targetctl with a
Python/rtslib_fb ExecStop that explicitly clears the kernel LIO state
(not just saves JSON), so the XFS backing store's file descriptor is
released before umount — preventing EBUSY stop timeouts on failover.
Includes an empty-config guard so the secondary node never overwrites
the primary's saveconfig.json with an empty one.
test-lab/ha/common.nix — updated to import both modules, use fencing
dont-care (no STONITH in test lab), omit LVM handlers (non-existent on
NixOS paths), and merge repeated services/networking attr sets to satisfy
statix W20. test-lab/ha/acceptance-tests.sh — final v4 with crm_standby
fix (pacemaker 3.x API).

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)

Replace the hardcoded hostname check (docker, pxe-boot) with a check
on config.fileSystems: any lxc-* host whose NixOS config declares an
NFS fileSystem entry is automatically made privileged. The script
already reads proxmoxLXC.privileged dynamically via
flake_target_lxc_privileged, so no logic change is needed there —
only the comment is updated to describe the new derivation.
Result: lxc-docker and lxc-pxe-boot (the two with NFS mounts) evaluate
as privileged=true; lxc-nix-cache, lxc-minimal, lxc-server,
lxc-tailscale-router, lxc-tor-relay evaluate as privileged=false.
Any future lxc-* host that declares an NFS mount gets the correct
privilege level for free without a separate manual edit.

The kernel's NFS client (FS_USERNS_MOUNT not set) rejects NFS mounts
from inside any unprivileged container's user namespace with EPERM —
AppArmor's mount=nfs feature only whitelists the AppArmor layer; the
VFS-level rejection happens before AppArmor is consulted.
lxc-pxe-boot mounts server.sweet.home:/tank/pxe-boot/images at
/mnt/pxe-images so nginx can serve large ISOs without filling the
container's root disk. Same pattern as lxc-docker (already privileged
for the same reason since it also mounts several NFS shares).
Operator action required: VMID 103 must be recreated as a privileged
container (the UID mapping on disk differs between privileged and
unprivileged; changing it in-place with pct set is unsafe). Rebuild
the tarball and use create-proxmox-resource.sh to replace it.

Proxmox LXC containers block the sunrpc filesystem (rpc_pipefs) via AppArmor
unless the container has `features: mount=nfs` set. NFSv4 requires rpc_pipefs
for client state management, so the mount fails outright in a default LXC.
Two fixes for the LXC case (config.boot.isContainer):
- Switch from nfsvers=4.2 to nfsvers=3,proto=tcp,nolock,nofail: NFSv3 doesn't
need rpc_pipefs at the protocol level, and nofail keeps boot clean if the
NFS server is unreachable.
- Add ConditionVirtualization=!container to var-lib-nfs-rpc_pipefs.mount via
systemd drop-in: NixOS pulls this unit into nfs-client.target for any NFS
fileSystems entry. With the condition, systemd skips (not fails) the unit in
containers, keeping nfs-client.target green and activation reporting clean.
Proxmox VM hosts (not isContainer) continue to use nfsvers=4.2 with
x-systemd.automount unchanged.
