Updates mount-data.nix to mount all docker shares from
nfs.storage.home (Pacemaker vip-storage, 192.168.20.229) over docker's
eth1/vmbr2 interface instead of server.sweet.home over the LAN.
Adds haStorageNfsFqdn variable to variables.nix for the storage.home
zone FQDN so mounts survive a future VIP renumber without a rebuild.
Storage root changes from /tank (server ZFS pool) to /srv/ha-data
(HA cluster XFS-over-DRBD). Share subpaths are unchanged.

NixOS's group activation uses plain groupmod, which silently skips the
GID change when SSSD exposes the same GID (50010) via the IPA
docker-access group through NSS. Add an activation script that runs
after the normal 'groups' step and applies groupmod --non-unique so the
local docker group can share GID 50010 with the SSSD-provided IPA group.
If the GID actually changes on a live system the script also restarts
docker.socket + docker.service so the socket is recreated with the new
GID.

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

The previous commit's networking.search fix was wrong. Confirmed live
on lxc-docker (vmid 105) after redeploying with it: `resolvectl query
server.sweet.home` started failing again, even though
`resolvectl query --interface=eth0 server.sweet.home` still resolved
correctly to the right IP via the LAN's real DNS server. The debug log
showed why -- adding a *global* search domain via networking.search
gave systemd-resolved a domain-matched but server-less "global" scope,
which it now prioritizes over eth0's correctly-configured scope for
every "*.sweet.home" query, silently sending them to public fallback
DNS (1.1.1.1 et al) instead, which of course returns NXDOMAIN for an
internal-only name. Bare single-label names (e.g. "server") were never
going to work either way -- systemd-resolved only ever tries LLMNR for
those, never DNS search-suffixing, regardless of configuration.
Reverts the networking.search addition and instead has
modules/docker/mount-data.nix build each NFS device string from
"${vars.nfsServerHost}.${vars.homeDomain}" (a plain FQDN, no dependency
on search-domain behavior at all) -- the same pattern
modules/raspi/mount-data.nix already uses for the Raspberry Pi's share
and for the identical reason.

Two compounding bugs, confirmed live on the running lxc-docker
container (vmid 102 on pve.sweet.home):
1. x-systemd.automount never works inside any Linux container --
systemd logs "Starting of <unit>.automount unsupported" for every
share and never mounts them. modules/docker/mount-data.nix and
modules/raspi/mount-data.nix now key off config.boot.isContainer
(set true by nixpkgs' proxmox-lxc.nix) to mount eagerly with
`nofail` there instead, while VM-based docker targets keep automount
unchanged.
2. The container's Proxmox `features` never included `mount=nfs`, so
AppArmor blanket-denies the nfs/rpc_pipefs mount syscalls NFS
needs ("permission denied"). scripts/env.sh's
PROXMOX_DEFAULT_LXC_FEATURES now includes mount=nfs;nfs4 for future
lxc-* containers -- the semicolon required quoting the --features
value in create-proxmox-resource.sh's remote pct-create command,
since it's sent as a raw string for the remote shell to parse and an
unquoted `;` would be read as a command separator.
The already-running container needs a matching `pct set --features`
plus a restart to pick this up -- that's an operator step outside this
repo.
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.

Zero W20 (repeated attribute keys), W10 (empty { ... }: variadic
pattern, use _: instead), and W04 (a = x.a instead of inherit)
warnings remain anywhere in the tree, and nixpkgs-fmt --check is
clean on all 46 .nix files.
Repeated-key merges go as deep as statix actually flags per file
(e.g. boot.loader.* nested under boot.loader = { ... } once the
outer boot.* merge exposed it as its own repeat) — every merge is a
pure attribute-path restructuring with no value changes, verified by
comparing config.system.build.toplevel.drvPath before/after for a
representative host per changed module plus a full 19-host + 4-package
eval sweep.
One indentation slip caught and fixed during this pass: nesting
modules/installer/common.nix's environment.etc."auto-install.sh".text
under an environment = { ... } block initially normalized the
script's shebang/set line indentation, which actually changes the
rendered file (Nix's '' string dedent treats it as real content, not
cosmetic whitespace) — reproduced the original's exact indentation
and reverified the rendered script is byte-identical to before.
modules/services/zfs/auto-mount-volumes.nix picked up formatting too;
worth noting it isn't imported by anything in this flake at all.

Several single-purpose modules sat at modules/ root or in the
services/ catch-all despite the repo's established pattern of one
directory per concern (tailscale/, beszel/, docker/, nix-cache/):
- remote-builder-client.nix -> nix-cache/ (always co-included with
nix-cache/client.nix in flake.nix's mkTarget, same buildType guard)
- set-locale.nix -> common/ (unconditionally imported by
common/configuration.nix already)
- enable-ip-forwarding.nix -> networking/
- rotate-traefik-logs.nix -> traefik/rotate-logs.nix
- services/docker-health-to-gotify.nix and services/nextcloud-cron-job.nix
-> docker/ (both only ever imported by the docker build type, same
as the rest of modules/docker/*)
Pure path moves plus import-path updates in flake.nix,
common/configuration.nix, and build-types/docker.nix — verified
eval-equivalent (drvPath-identical) across representative hosts.

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.
