fix(tailscale-router): stop dnsmasq from intercepting host DNS queries

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).

+script — not an inline Nix string. It sources `scripts/env.sh` for
+`LAN_DOMAIN` itself (same as every other script in `scripts/`), so it
+behaves identically whether it's run straight from a git checkout (e.g.
+manually, from a stock NixOS ISO that isn't this repo's own installer
+image) or from inside the built installer image. That's also why it's
+baked in at `/etc/nixos-installer/installer/auto-install.sh` rather than a
+flat `/etc/auto-install.sh` — `modules/installer/common.nix` bakes
+`scripts/env.sh` in alongside it at `/etc/nixos-installer/env.sh`,
+preserving the same relative layout (`installer/auto-install.sh` ->
+`../env.sh`) the checked-out repo has, so the script's own
+`source ".../env.sh"` line resolves correctly in both places without any
+Nix-level templating.
+
+Once running, it:
 
 1. Queries `nixosConfigurations` from this flake over the network (`git+https://<lanDomain>/beatzaplenty/nixos.git`) — this happens at *install* time, not build time, so a generic installer image always sees whatever hosts are currently committed, without needing a rebuild.
 2. Presents them as a menu; confirms the choice.

+# IP Addressing Scheme
+
+## Subnets
+
+| Subnet | CIDR | Purpose | Routed? |
+|---|---|---|---|
+| LAN | `192.168.2.0/24` | General LAN — clients and infrastructure | Yes (gateway .254) |
+| Storage | `192.168.4.0/29` | HA file server DRBD replication | No — internal `vmbr1` only, no uplink |
+
+The storage subnet never leaves pve1. `vmbr1` is a Proxmox Linux bridge with no physical port
+attached; traffic between the two HA file server VMs stays in-kernel.
+
+The host octet is consistent across subnets for any host that has multiple interfaces — e.g.
+ha-node1 is always `.228` (LAN: `192.168.2.228`, storage: `192.168.4.228`).
+
+---
+
+## LAN — 192.168.2.0/24
+
+### Address map
+
+| Range | Purpose |
+|---|---|
+| .1–.9 | Reserved, never assign |
+| .10–.59 | Client DHCP pool (router-assigned) |
+| .60–.219 | Unallocated buffer |
+| .220–.229 | Virtual nodes (VMs / LXC containers) |
+| .230–.239 | Expansion buffer (reserved, unallocated) |
+| .240–.249 | Physical nodes (bare-metal hosts) |
+| .250–.253 | Network services |
+| .254 | Router / gateway |
+
+### Network services (.250–.253)
+
+| IP | Hostname | Role |
+|---|---|---|
+| `192.168.2.254` | router | Gateway (TP-Link) |
+| `192.168.2.253` | domain-controller | FreeIPA — authoritative DNS for `sweet.home`, Kerberos, LDAP |
+| `192.168.2.250`–`.252` | — | Reserved for future network services |
+
+### Physical nodes (.240–.249)
+
+| IP | Hostname | Role |
+|---|---|---|
+| `192.168.2.245` | pve1 | Proxmox VE hypervisor |
+| `192.168.2.244` | pbs | Proxmox Backup Server |
+| `192.168.2.243` | nixos | Bare-metal workstation (`baremetal-gui`) |
+| `192.168.2.246`–`.249` | — | Reserved — second Proxmox node and associated services |
+| `192.168.2.240`–`.242` | — | Reserved |
+
+pve1 sits mid-range deliberately so a second Proxmox node can slot in on either side.
+
+### Virtual nodes (.220–.229)
+
+All VMs and LXC containers run on pve1.
+
+| IP | Hostname | Role | Status |
+|---|---|---|---|

+| `192.168.2.227` | ha-node2 | HA file server node 2 (DRBD + XFS + iSCSI) | Future |
+| `192.168.2.226` | server | Current NFS/ZFS file server — retires when HA is live | Retiring |
+| `192.168.2.225` | docker | Docker / Traefik stack | Active |
+| `192.168.2.224` | nix-cache | Nix binary cache + remote builder | Active |
+| `192.168.2.223` | pxe-boot | PXE / TFTP / HTTP netboot server | Active |
+| `192.168.2.222` | tailscale-router | Tailscale exit node / router | Active |
+| `192.168.2.221` | tor-relay | Tor relay | Active |
+| `192.168.2.220` | pdm | Proxmox Deploy Manager | Active |
+
+### Client DHCP pool (.10–.59)
+
+Assigned by the router. DNS option points to `192.168.2.253` (domain-controller).
+
+Devices in this range: phones, laptops, IoT, Canon printer, any non-infrastructure host.
+No static reservations for infrastructure hosts — all infra uses static IP configuration
+on the guest itself (not DHCP reservations), so IPs survive VM recreation regardless of
+MAC address churn.
+
+---
+
+## Storage network — 192.168.4.0/29
+
+Internal to pve1 only. Proxmox bridge `vmbr1`, no physical NIC attached.
+
+| IP | Hostname | Interface role |
+|---|---|---|
+| `192.168.4.228` | ha-node1 | DRBD replication NIC |

+### Cutover notes
+
+- **Do domain-controller first** — it becomes the DNS server; everything else depends on it
+  having its new IP and FreeIPA DNS configured before Pi-hole is retired.
+- **pve1 last among physical hosts** — changing the Proxmox management IP drops the web UI
+  briefly; all guests keep running.
+- **Update Pi-hole custom.list / FreeIPA DNS A records** to new IPs before flipping any host,
+  so name resolution stays valid throughout the migration.
+- **variables.nix already updated** for `pxeServerIp` (.247→.223), `pbsIp` (.108→.244), and
+  new `domainControllerIp` (.253). Rebuild affected hosts after renumbering.
+- **Router DHCP**: once domain-controller is at .253 and FreeIPA DNS is serving `sweet.home`,
+  switch router DHCP on with pool .10–.59 and DNS option pointing to .253; retire Pi-hole CT.
+- **Pi-hole's iPXE dnsmasq config** (`99-ipxe-chainload.conf`) moves to the pxe-boot CT as a
+  dnsmasq proxy-mode config before Pi-hole is decommissioned.

+# Network Cutover Plan
+
+Moves the LAN from the current flat/Pi-hole-managed state to the new IP scheme
+defined in `docs/ip-addressing.md`. Works in five independent stages — each
+stage is safe to pause after and resume later. Rollback steps are given at
+every point where something can break.
+
+**Before starting anything:** confirm you have
+- SSH access to `192.168.2.138` (domain-controller, current IP)
+- SSH access to `192.168.2.250` (pve1)
+- Browser access to Pi-hole admin at `http://192.168.2.253`
+- Browser access to router admin at `http://192.168.2.254`
+- The FreeIPA `admin` password to hand
+
+---
+
+## Stage 1 — Prepare FreeIPA DNS (zero downtime)
+
+Everything here is additive. Pi-hole keeps running. Nothing breaks if you stop
+mid-stage.
+
+### 1a. Add NextDNS forwarders
+
+```bash
+ssh wayne@192.168.2.138
+kinit admin          # enter FreeIPA admin password when prompted
+ipa dnsconfig-mod \
+  --forwarder=45.90.28.142 \
+  --forwarder=45.90.30.142 \
+  --forward-policy=only
+```
+
+**Verify external resolution works through FreeIPA before continuing:**
+```bash
+dig @127.0.0.1 google.com +short   # must return an IP, not SERVFAIL
+```
+
+### 1b. Add A records for every host at their CURRENT IPs
+
+These represent the live state now. You'll update each record to the new IP
+when you renumber that host in Stage 5.
+
+```bash
+ipa dnsrecord-add sweet.home pve1             --a-rec 192.168.2.250
+ipa dnsrecord-add sweet.home pbs              --a-rec 192.168.2.108
+ipa dnsrecord-add sweet.home nixos            --a-rec 192.168.2.119
+ipa dnsrecord-add sweet.home server           --a-rec 192.168.2.252
+ipa dnsrecord-add sweet.home docker           --a-rec 192.168.2.249
+ipa dnsrecord-add sweet.home nix-cache        --a-rec 192.168.2.120
+ipa dnsrecord-add sweet.home pxe-boot         --a-rec 192.168.2.247
+ipa dnsrecord-add sweet.home tailscale-router --a-rec 192.168.2.121
+ipa dnsrecord-add sweet.home tor-relay        --a-rec 192.168.2.107
+ipa dnsrecord-add sweet.home pdm              --a-rec 192.168.2.248
+ipa dnsrecord-add sweet.home router           --a-rec 192.168.2.254
+```
+
+### 1c. Clean up stale reverse-zone PTR records
+
+FreeIPA already has PTR records from an earlier import but some are wrong.
+Fix them now so reverse DNS is accurate from day one.
+
+```bash
+# Remove stale "win11" entry at .250 (should be pve1)
+ipa dnsrecord-del 2.168.192.in-addr.arpa 250 --ptr-rec win11.
+ipa dnsrecord-add 2.168.192.in-addr.arpa 250 --ptr-rec pve1.sweet.home.
+
+# Fix unqualified PTR records (missing .sweet.home. suffix)
+ipa dnsrecord-mod 2.168.192.in-addr.arpa 108 --ptr-rec pbs.sweet.home.
+ipa dnsrecord-mod 2.168.192.in-addr.arpa 248 --ptr-rec pdm.sweet.home.
+ipa dnsrecord-mod 2.168.192.in-addr.arpa 249 --ptr-rec docker.sweet.home.
+ipa dnsrecord-mod 2.168.192.in-addr.arpa 252 --ptr-rec server.sweet.home.
+
+# Add any missing PTR records
+ipa dnsrecord-add 2.168.192.in-addr.arpa 119 --ptr-rec nixos.sweet.home.
+ipa dnsrecord-add 2.168.192.in-addr.arpa 120 --ptr-rec nix-cache.sweet.home.
+ipa dnsrecord-add 2.168.192.in-addr.arpa 121 --ptr-rec tailscale-router.sweet.home.
+ipa dnsrecord-add 2.168.192.in-addr.arpa 247 --ptr-rec pxe-boot.sweet.home.
+ipa dnsrecord-add 2.168.192.in-addr.arpa 254 --ptr-rec router.sweet.home.
+```
+
+### 1d. Point domain-controller's own DNS at itself
+
+```bash
+sudo nmcli connection modify "System eth0" ipv4.dns "127.0.0.1"
+sudo nmcli connection up "System eth0"
+```
+
+**Verify:**
+```bash
+dig pve1.sweet.home +short          # must return 192.168.2.250
+dig google.com +short               # must return an IP (NextDNS forwarding)
+```
+
+**Rollback 1d:** `sudo nmcli connection modify "System eth0" ipv4.dns "192.168.2.253" && sudo nmcli connection up "System eth0"`
+
+---
+
+## Stage 2 — Move pxe-boot DHCP options off Pi-hole (zero downtime)
+
+Pi-hole's dnsmasq currently serves the iPXE boot options via
+`99-ipxe-chainload.conf`. Before Pi-hole is retired, that config must move to
+the pxe-boot CT running dnsmasq in proxy mode so PXE boot keeps working.
+
+### 2a. Add dnsmasq proxy config to the pxe-boot NixOS module
+
+In `modules/build-types/pxe-boot.nix`, add:
+
+```nix
+services.dnsmasq = {
+  enable = true;
+  settings = {
+    # Proxy mode: respond only to PXE DHCP requests, leave normal leases to router
+    dhcp-range = [ "192.168.2.0,proxy" ];
+    # iPXE client detection
+    dhcp-match = [
+      "set:ipxe,175"
+      "set:efi64,option:client-arch,7"
+      "set:efi64,option:client-arch,9"
+    ];
+    dhcp-userclass = "set:ipxe,iPXE";
+    # Boot file selection
+    dhcp-boot = [
+      "tag:ipxe,tag:efi64,http://${vars.pxeServerIp}/boot.ipxe"
+      "tag:ipxe,http://${vars.pxeServerIp}/boot.ipxe"
+      "tag:efi64,ipxe.efi,,${vars.pxeServerIp}"
+      "undionly.kpxe,,${vars.pxeServerIp}"
+    ];
+  };
+};
+```
+
+### 2b. Rebuild and deploy the pxe-boot CT
+
+```bash
+# On pve1 — build the new tarball
+nix build .#lxc-pxe-boot.config.system.build.tarball
+
+# Verify dnsmasq starts correctly in the CT after deploy
+ssh nixos@192.168.2.247 systemctl status dnsmasq
+```
+
+### 2c. Remove the iPXE config from Pi-hole
+
+In the Pi-hole CT, remove `/etc/dnsmasq.d/99-ipxe-chainload.conf` and
+restart the FTL service:
+
+```bash
+ssh wayne@pve1.sweet.home \
+  "sudo pct exec 100 -- bash -c 'rm /etc/dnsmasq.d/99-ipxe-chainload.conf && systemctl restart pihole-FTL'"
+```
+
+**Verify:** PXE boot a test machine — it should still get an iPXE response and
+reach the boot menu.
+
+**Rollback 2c:** restore the file from the Pi-hole config backup at
+`/etc/pihole/config_backups/` and restart pihole-FTL.
+
+---
+
+## Stage 3 — DHCP migration: Pi-hole → router (brief maintenance window)
+
+**Do this in the evening.** Existing DHCP leases stay valid during the
+switchover so connected devices don't drop — only new lease requests fail
+during the gap, which is under 60 seconds if you follow the steps in order.
+
+The key: configure the router's DHCP DNS option to point at `.253` (Pi-hole's
+current IP). This way, all new leases issued by the router still get the same
+DNS server address — clients never need to change their DNS config. When Pi-hole
+is retired and the DC takes `.253` in Stage 4, `.253` just starts answering
+differently. No client reconfiguration.
+
+### 3a. Pre-configure router DHCP (do not enable yet)
+
+Log into `http://192.168.2.254`, find the DHCP settings and fill in — but
+leave DHCP **disabled** until step 3b:
+
+| Setting | Value |
+|---|---|
+| Start IP | 192.168.2.10 |
+| End IP | 192.168.2.59 |
+| Subnet mask | 255.255.255.0 |
+| Gateway | 192.168.2.254 |
+| Primary DNS | 192.168.2.253 |
+| Secondary DNS | *(leave blank)* |
+| Lease time | 24h |
+
+Save without enabling.
+
+### 3b. Switchover (do steps in quick succession)
+
+1. **Disable Pi-hole DHCP:** Pi-hole admin UI → Settings → DHCP → uncheck
+   "DHCP server enabled" → Save
+2. **Enable router DHCP** immediately after step 1
+
+### 3c. Verify router DHCP is working
+
+On a phone or laptop, disconnect from WiFi and reconnect (or run
+`sudo dhclient -r && sudo dhclient` on a Linux host):
+
+```bash
+ip addr show        # IP should be in 192.168.2.10–59 range
+dig google.com      # should resolve (Pi-hole DNS still running at .253)
+dig pve1.sweet.home # should resolve via FreeIPA at .138 (relayed via Pi-hole)
+```
+
+Wait 10–15 minutes for the most active devices to renew their leases. There's
+no need to wait for all leases to expire before proceeding.
+
+**Rollback 3b:** Re-enable Pi-hole DHCP. Disable router DHCP. Done — existing
+leases remain valid so most devices are unaffected.
+
+---
+
+## Stage 4 — Move domain-controller from .138 to .253
+
+Pi-hole lives at `.253`. The DC must take `.253` the moment Pi-hole stops so
+clients that still have `.253` as their DNS server don't notice the change.
+Script these commands in advance and run them in rapid succession.
+
+**Pre-stage: have this SSH command ready before running step 4a:**
+```bash
+ssh wayne@192.168.2.138 "
+  sudo nmcli connection modify 'System eth0' \
+    ipv4.addresses '192.168.2.253/24' \
+    ipv4.gateway '192.168.2.254' \
+    ipv4.dns '127.0.0.1' \
+    ipv4.method manual && \
+  sudo nmcli connection up 'System eth0'
+"
+```
+
+**Also update the Proxmox VM config to match (run from pve1):**
+```bash
+sudo qm set 108 \
+  --ipconfig0 ip=192.168.2.253/24,gw=192.168.2.254 \
+  --nameserver 192.168.2.253
+```
+
+### 4a. Stop Pi-hole
+
+```bash
+ssh wayne@pve1.sweet.home "sudo pct stop 100"
+```
+
+### 4b. Immediately: change DC's IP to .253
+
+Run the pre-staged SSH command from above. You have ~30 seconds before any
+client notices Pi-hole is gone. If SSH to `.138` refuses (the IP is already
+changing), open a Proxmox console to VM 108 and run the `nmcli` commands
+there.
+
+### 4c. Update Proxmox VM config
+
+Run the pre-staged `qm set 108` command from above.
+
+### 4d. Verify
+
+```bash
+ssh wayne@192.168.2.253   # must connect (new DC IP)
+dig @192.168.2.253 pve1.sweet.home +short   # must return 192.168.2.250
+dig @192.168.2.253 google.com +short        # must return an IP
+```
+
+From a client device that renewed its DHCP lease in Stage 3:
+```bash
+cat /etc/resolv.conf    # should show 192.168.2.253
+dig pve1.sweet.home     # should resolve
+```
+
+**Rollback 4:** `ssh wayne@pve1.sweet.home "sudo pct start 100"`. Change DC IP
+back to .138 via Proxmox console. This restores full Pi-hole DNS/DHCP service.
+Leave Pi-hole CT stopped-but-intact for 48 hours before deleting it.
+
+---
+
+## Stage 5 — Host renumbering (one at a time, any order)
+
+For each host:
+1. Update FreeIPA DNS A record and PTR record to the new IP
+2. Change the static IP on the host itself
+3. Verify SSH to new IP
+4. Update `variables.nix` if that host has an IP variable (pxe-boot, pbs — already done in this PR)
+
+**FreeIPA record update template** (run as admin on domain-controller):
+```bash
+ipa dnsrecord-mod sweet.home <hostname> --a-rec <new-ip>
+ipa dnsrecord-del 2.168.192.in-addr.arpa <old-last-octet> --ptr-rec <hostname>.sweet.home.
+ipa dnsrecord-add 2.168.192.in-addr.arpa <new-last-octet> --ptr-rec <hostname>.sweet.home.
+```
+
+### Renumbering order
+
+| # | Host | Old IP | New IP | How to change IP |
+|---|---|---|---|---|
+| 1 | nixos workstation | .119 | .243 | NetworkManager on guest; or `nmcli connection modify` |
+| 2 | nix-cache | .120 | .224 | `pct set 102 --net0 name=eth0,bridge=vmbr0,ip=192.168.2.224/24,gw=192.168.2.254` then `pct reboot 102` |
+| 3 | tailscale-router | .121 | .222 | Static config on guest; check Tailscale ACLs if IP is referenced there |
+| 4 | tor-relay | .107 | .221 | `pct set 104 --net0 name=eth0,bridge=vmbr0,ip=192.168.2.221/24,gw=192.168.2.254` then `pct reboot 104` |
+| 5 | pdm | .248 | .220 | `pct set 106 --net0 name=eth0,bridge=vmbr0,ip=192.168.2.220/24,gw=192.168.2.254` then `pct reboot 106` |
+| 6 | pxe-boot | .247 | .223 | `pct set 103 --net0 name=eth0,bridge=vmbr0,ip=192.168.2.223/24,gw=192.168.2.254` then rebuild NixOS (already updated in variables.nix) |
+| 7 | server | .252 | .226 | Static config on guest; NFS clients (docker) lose mounts briefly — they remount automatically |
+| 8 | docker | .249 | .225 | Static config on guest; do this after server is at .226 |
+| 9 | pbs | .108 | .244 | Static config on PBS host itself; update in `pbsIp` already done in variables.nix |
+| 10 | pve1 | .250 | .245 | Edit `/etc/network/interfaces` on the Proxmox host — see below |
+
+### pve1 renumber (step 10 — do last)
+
+All guests keep running; only the Proxmox web UI is briefly unreachable.
+
+```bash
+ssh wayne@pve1.sweet.home
+

+# Rebuild any NixOS hosts that reference pbsIp or pxeServerIp to pick up
+# the updated variables.nix values (pxe-boot mandatory; others as convenient)
+```
+
+---
+
+## Rollback summary
+
+| What broke | How to roll back |
+|---|---|
+| FreeIPA DNS not resolving | Check `systemctl status named` on DC; restart if failed |
+| FreeIPA DNS unreachable | `pct start 100` on pve1 (restores Pi-hole) |
+| Router DHCP not handing out leases | Re-enable Pi-hole DHCP; disable router DHCP |
+| DC unreachable after IP change | Proxmox console on VM 108 → `nmcli connection up "System eth0"` with old IP |
+| Host unreachable after renumber | Proxmox console → revert IP; or `pct set <id> --net0 ...` old IP and reboot CT |
+| pve1 web UI gone after renumber | SSH to .245 and check `/etc/network/interfaces`; if wrong, fix and restart networking |

+non-blocking on server unavailability); for a Proxmox VM it uses NFSv4.2
+with `x-systemd.automount` (lazy, triggered on first access).
+
+When running as `lxc-pxe-boot`, the Proxmox container must have
+`features: nesting=1,mount=nfs` (at minimum) in its Proxmox config. `nesting=1`
+is required by systemd 260+ for credential isolation (user namespace creation
+and internal move-mounts); without it, AppArmor denies both, and every
+systemd service that uses `PrivateUsers`, `PrivateDevices`, or credential
+passing fails on boot. `mount=nfs` allows the NFSv3 mount. Both are set
+automatically by `scripts/proxmox/create-proxmox-resource.sh` (via
+`PROXMOX_DEFAULT_LXC_FEATURES` in `scripts/env.sh` which defaults to
+`nesting=1,keyctl=1,mount=nfs;nfs4`). If you ever change these features
+manually via `pct set`, be sure to include both — `pct set` replaces the

+# LIO iSCSI target service (targetctl) for NixOS HA clusters.
+#
+# Provides the targetctl.service that saves/restores LIO configuration from
+# /etc/target/saveconfig.json.  Pacemaker manages this service via its
+# systemd resource agent (class="systemd" type="targetctl").
+#
+# Why ExecStop is not simply "targetctl save":
+#   targetctl save writes the LIO config to JSON but does NOT remove the LIO
+#   target from the kernel's configfs.  As a result, any fileio backing store
+#   that LIO has open (e.g. iscsi-lun.img on an XFS-over-DRBD filesystem)
+#   stays referenced in the kernel.  The subsequent XFS umount from the
+#   Filesystem OCF resource then returns EBUSY and either hangs for the full
+#   op-stop timeout or fails outright, blocking the entire failover.
+#
+#   The ExecStop script here additionally tears down the kernel LIO state
+#   via rtslib_fb after saving, so the backing-store file descriptor is
+#   released and umount succeeds immediately.
+#
+# Empty-config guard:
+#   The save step is skipped when no iSCSI targets are currently active.
+#   This prevents the secondary node (where LIO was never started) from
+#   overwriting a valid saveconfig.json with an empty one when Pacemaker

+# Pacemaker + Corosync HA stack for NixOS with known-good workarounds.
+#
+# Issues fixed here (confirmed through live testing on NixOS 25.11):
+#
+# 1. StateDirectory ownership reset: systemd's StateDirectory=pacemaker
+#    creates /var/lib/pacemaker owned root:root.  pacemaker-based (the CIB
+#    daemon) runs as the hacluster user and calls pcmk__daemon_can_write,
+#    which requires the CIB directory to be owned by hacluster or be
+#    group-writable by haclient.  Workaround: remove StateDirectory and let
+#    ExecStartPre create every required subdirectory with correct ownership.
+#
+# 2. HA_SBIN_DIR wrong path: ocf-shellfuncs sets HA_SBIN_DIR to the Nix
+#    store path of the resource-agents derivation's /sbin, which doesn't
+#    exist.  The DRBD OCF agent uses ${HA_SBIN_DIR}/crm_master, so it exits
+#    127 without this override.  Fix: export HA_SBIN_DIR=/run/current-system/sw/bin.
+#
+# 3. Broad PATH for OCF agents: the resource executor (pacemaker-execd) runs
+#    OCF agent scripts as children.  NixOS provides no implicit PATH for
+#    system services; without an explicit PATH the agents can't find ip, ss,
+#    mount, umount, drbdadm, etc.
+#
+# 4. FUSER=true: the Filesystem OCF agent calls check_binary $FUSER (default:
+#    fuser from psmisc), which is not installed.  Setting FUSER=true makes
+#    check_binary succeed (true is always in PATH) and the subsequent
+#    "$FUSER -km $mountpoint" becomes a no-op.  Pair with force_unmount=false
+#    on each Filesystem resource unless you want lazy unmount behaviour.

+# Add a NixOS host to the FreeIPA domain and produce a sops-encrypted keytab
+# at secrets/<hostname>.keytab, ready for modules/ipa/client.nix.
+#
+# One command replaces three error-prone manual steps:
+#   1. ipa host-add on the domain controller
+#   2. ipa-getkeytab on the domain controller + SCP back
+#   3. sops encrypt in-place (must be at secrets/<hostname>.keytab for
+#      the creation rule to match -- the common mistake that breaks sops)
+#
+# Usage:
+#   scripts/ipa/create-nixos-ipa-host-account.sh [options] <hostname>
+#
+# Arguments:
+#   <hostname>       Short hostname, e.g. "tailscale-router". The FQDN is
+#                    derived as <hostname>.<HOME_DOMAIN>.
+#
+# Options:
+#   --ip <addr>      Register this IP with the IPA host record (optional).
+#   --dc <host>      SSH to this host for ipa-getkeytab.
+#                    Default: $IPA_SERVER (from env.sh / environment).
+#   --dc-user <u>    SSH user on the domain controller. Default: wayne.
+#   --dry-run        Print what would be done without making any changes.
+#   -h, --help       Show this message.
+#
+# Prereqs:
+#   1. Run from the repo root (so .sops.yaml and secrets/ are found).
+#   2. SSH access to the domain controller as --dc-user (default: wayne)
+#      with passwordless sudo (or sudo cached). IPA commands and kinit run
+#      as root via sudo so the Kerberos ticket is in root's cache where all
+#      ipa tools expect it. If there's no valid ticket, the script runs
+#      `sudo kinit admin` interactively — you'll be prompted for the IPA
+#      admin password once. The password never touches this script.
+#   3. The host's age key(s) must already be in .sops.yaml. Run
+#      scripts/secrets/sync-host-keys.sh <flake-target> first so the host
+#      can decrypt its own keytab on boot. This script adds the .sops.yaml
+#      creation rule for secrets/<hostname>.keytab automatically, but the
+#      host age key anchor (&lxc-<hostname> etc.) must already exist.

+#      Fix: scp the registered key back and restore it (needs sudo once per host).
+#      To push new keys proactively (before drift, e.g. right after

+#      a token GitHub rejects (401), blocking any rebuild that fetches disko or
+#      other public GitHub flake inputs.
+#      Fix: empty the rendered file so nix makes unauthenticated requests instead.

+#      re-renders the correct new token automatically after the first successful
