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).

ipa-getkeytab runs as root via sudo so the temp file is root-owned;
scp as wayne gets Permission denied. Pipe through `sudo cat` over SSH

Single command to enroll a NixOS host in FreeIPA and produce a
sops-encrypted keytab at secrets/<hostname>.keytab:
- Adds the .sops.yaml creation rule automatically (with all registered
platform-variant age keys as recipients)
- SSHes to the domain controller to run ipa host-add + ipa-getkeytab
- Refreshes the admin Kerberos ticket via `ssh -t ... kinit admin` if
missing or expired, so no manual kinit step is needed
- SCPs the keytab and encrypts it in-place with sops (file must be at
secrets/<hostname>.keytab before encryption so the path-based creation
rule matches — the common failure point when doing this manually)
Also adds HOME_DOMAIN and IPA_SERVER to scripts/env.sh, matching
variables.nix's homeDomain/ipaServer (same manual-sync pattern as
NIX_CACHE_HOST/LAN_DOMAIN).

sops matches creation rules against the input file path, so encrypting

ipa-getkeytab confirmed ipa.sweet.home doesn't respond to LDAP;

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
public TLD with DNSimple nameservers. The forward zone must use the
tailnet-specific subdomain (vars.tailnetDomain, e.g. tail13f623.ts.net)
instead. Update dnsmasq server selector and comments to match.

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

vars.pxeServerIp was already set to the post-renumber target (.223) but the
pxe-boot CT is still at .247, so dnsmasq was advertising .223 as the TFTP server

After the proxy DHCP handshake, the UEFI client queries the PXE boot
server on UDP port 4011 to get the actual boot filename. This port was
not open in the NixOS firewall, so all four PXE discovery attempts from

never received the packets.

dnsmasq 2.93 does not send proxy DHCP offers from dhcp-boot alone in proxy
mode — pxe-service is required to trigger proxy offers for the initial boot.
Replace the dhcp-boot-based arch detection with pxe-service entries for
arch 0 (BIOS), 7 (EFI BC / OVMF), and 9 (EFI x86-64), then use dhcp-boot
only for the iPXE second-boot HTTP chain (tag:ipxe clients). Add log-dhcp
for post-deploy verification.

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

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
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

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)

SOPS_AGE_KEY_FILE was set in hosts/nixos/home.nix sessionVariables with a
literal ~ that Home Manager injects as-is into the environment. In bash,
tilde expansion does not happen inside double-quoted variable references, so
DEFAULT_SOPS_AGE_KEY_FILE resolved to ~/... literally and the -s file-existence
check in ensure_admin_decrypt_key silently failed. The script then generated
a brand-new age key (to ~/... relative to the repo root) while the real admin
key at ~/.config/sops/age/keys.txt went untouched -- making it appear the key
was lost when it was actually still intact.
Fix the home.nix root cause by using config.home.homeDirectory so the path
is fully resolved. Add tilde expansion in ensure_admin_decrypt_key as a
belt-and-suspenders guard for any caller whose environment has the same issue.
Also replace the auto-generate-a-new-key fallback with a hard failure: auto-
generating a new admin key is never useful (it cannot decrypt existing secrets)
and created serious confusion about whether the original key was lost.

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.

- Correct the NFS path from /tank/proxmox/pxe-images to /tank/pxe-boot/images

- Clarify that LXC uses NFSv3+nolock while VM uses NFSv4.2+automount
- Add explicit note that lxc-pxe-boot needs features: nesting=1,mount=nfs and
why: nesting=1 is required by systemd 260+ for userns/credential isolation
(AppArmor denies userns_create without it), mount=nfs for NFSv3 access.
pct set replaces the whole features string — include both or the container
will fail to boot.

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.

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.

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

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

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.

--pre-format-files placed the key on the QEMU builder VM's rootfs, not the
target disk. nixos-install chroots into the target and runs sshd-keygen, which
found no key in the chroot and generated a fresh (unregistered) one. sops then
could not decrypt on first boot because the key didn't match .sops.yaml, leaving
both root and nixos with '!' in /etc/shadow even after mutableUsers = false was
set (hashedPasswordFile pointed to paths sops never wrote).
Fix modules/platforms/proxmox.nix to embed the clan SSH host key in
environment.etc via NIXOS_HOST_KEYS_DIR at eval time -- the same pattern
lxc.nix uses. nixos-install's own activation places the key on the target disk,
sshd-keygen finds it already present and skips generation, and sops decrypts
correctly on first boot. Includes the same preserveSshHostKey/restoreSshHostKey
activation scripts as lxc.nix so subsequent nixos-rebuild switch calls (without
NIXOS_HOST_KEYS_DIR) don't remove the key as "obsolete" from environment.etc.
Update create-proxmox-resource.sh: switch VM builds from

Three bugs combined to leave every VM build with a shell but no boot disk:
1. The remote build script moved the raw image to /var/lib/vz/import/ before
qm importdisk could use it. If the mv failed (cross-filesystem copy, sudo
path, or any other reason) the remote script exited non-zero -- but the
local script's set -e handling of the SSH heredoc was inconsistent, so
qm create sometimes ran anyway, leaving a diskless VM shell.
Fix: skip the mv entirely. The diskoImagesScript writes <hostname>.raw into
its CWD (the remote repo dir, $out = $PWD at invocation). Import directly
from that path; clean it up after a successful import.
2. The qm importdisk output regex expected "Successfully imported disk as '...'"
but current Proxmox emits "unusedN: successfully imported disk '...'"
(lowercase, no "as"). The grep returned no match and exited 1.
3. The disk_id assignment used $(... | grep ...) without || true inside the
substitution. With set -euo pipefail, a non-zero grep exit aborts the
script before the fallback could run -- so the VM was always left with an
unattached unused0 disk.
Fix: update the primary regex to match the actual PVE format; add || true
inside the substitution so set -e never fires on a grep miss; add a qm
config fallback (scan for unusedN: lines) that works regardless of PVE
output format changes.

When a proxmox-* disk image is built, activation runs during the image
build without a valid sops age key (the SSH host key doesn't exist yet),
so root and nixos land in /etc/shadow with locked '!' entries. With the
default mutableUsers = true, update-users-groups.pl preserves existing
shadow entries for accounts that already exist, so hashedPasswordFile is
silently ignored on every subsequent boot — passwords are never fixed.
Setting mutableUsers = false forces update-users-groups.pl to apply
hashedPasswordFile unconditionally on every activation. On first real
boot the sops-decrypted hash is now written regardless of whether the
account already existed in shadow from the image build.

qm importdisk in QEMU 11.x outputs lowercase "successfully imported disk
as '...'" rather than the capitalised form the original grep expected.
The case mismatch made disk_id always empty, which caused the script to
exit 1 after qm create had already run -- leaving the VM with only an
EFI disk, no scsi0, and boot order still set to net0.
Fix by adding -i (case-insensitive) to the grep. Both the old capitalised
format (where the disk id had an "unused0:" prefix inside the quotes) and
the new lowercase format are handled correctly: the sed strip of unused0:
is preserved for backward compatibility, and the regex result is identical
either way.
Also add an early warning when --disk-size is passed for --type vm: the
flag is LXC-only for create mode and was silently ignored, leaving users
expecting a different size than the proxmoxImageSize in variables.nix.
