Headscale is the tailnet control server every host's services/tailscale.nix
already points at (--login-server=https://vpn.mgaction.town). MagicDNS
base_domain "hosts.mgaction.town" matches the "jupiter.hosts.mgaction.town"
names already used in this repo's Caddy vhosts.
Headplane is its web UI, running as headscale's own user (native process
integration, no container). No OIDC wired up - log in with a headscale API
key generated on the box. Both proxied through Caddy; headscale's vhost
needs flush_interval -1 since its node-update endpoint is a long-poll.

Local Postgres, peer-authed over the unix socket (the "zitadel" role is
granted createdb+createrole and doubles as both the runtime and bootstrap
DB user - no password anywhere). TLS terminates at Caddy; Zitadel listens
on localhost:8080 and is proxied at auth.mgaction.town.
Master key and admin bootstrap password come from sops - the admin
password specifically needs the sops.templates -> rendered-file route
(services.zitadel.steps would leak it into the world-readable Nix store),
same pattern as mercury's pihole.env.

Caddy only proxies HTTP; git-over-ssh to gitea needs a raw TCP forward
since gitea's built-in SSH server (jupiter:2222) isn't otherwise reachable
from the public internet. socat forwards the VPS's public :2222 over the
tailnet. Matches what's now live on the (still-Debian) VPS - ready to drop
in once neptun gets migrated to this NixOS config.

- sabnzbd, prowlarr, sonarr, radarr, clonarr, seerr, cinephage, mediamanager
services, wired into jupiter with LAN Caddy vhosts.
- Gitea: migrated the old ZimaOS docker instance's data (sqlite db, 4 repos,
no LFS objects) into the NixOS module's default stateDir layout. HTTP via
Caddy; git SSH on its own built-in server at :2222 (not :222 - the unpriv
gitea user can't bind <1024).
- mediamanager-nix flake input for the mediamanager service.

- services/pihole.nix: official pihole/pihole:2026.07.2 via podman, host net,
caps NET_ADMIN/NET_RAW/SYS_NICE/CHOWN; FTLCONF_* env config (upstream unbound,
DHCP 50-200, static lease jupiter, .sol domain, local records)
- unbound: resolveLocalQueries=false (was hijacking resolv.conf to :53 -> boot
DNS deadlock; the real root cause of the earlier failures too)
- password via sops FTLCONF env file; /var/lib/pihole created via tmpfiles
- VM-verified: mercury.sol/jupiter.sol/external all resolve, 0 restarts
Pi's vfat partition isn't mounted at runtime (u-boot reads it pre-boot), so
/boot/firmware doesn't exist -> keyFile moved to the always-mounted root fs.
deploy flash now drops it on the ext4 root partition.
pihole.toml is nix-managed read-only so 'pihole setpassword' fails. pihole-FTL
reads FTLCONF_* env vars (override the toml) — render an env file from the sops
secret pihole_webpassword and feed it via EnvironmentFile. Password stays out of
repo/store. VERIFIED in VM: FTLCONF_webserver_api_password -> API login works.
- after dd, if ~/.config/homelab/<config>/age.txt exists, mount the FAT boot
partition and drop it as sops-age.txt (mercury). Key stays off-repo + out of
the store + out of the image; no manual mount step.
- per-host darman_password (distinct hash) in secrets/{jupiter,vps,mercury}.yaml
-> hashedPasswordFile; different console password per host (ssh still key-only)
- mercury: dedicated age key (on boot partition post-flash), sops-nix wired
- AdGuard: module has no secret hook + writable config -> mutableSettings=true,
admin password set via web setup on first boot (never in repo/store)
- nixosConfigurations.mercury: aarch64, sd-image-aarch64, imports common.nix
- static net placeholders (CHANGE-ME), hostname mercury
- DNS service left undecided: commented pihole (services.pihole-ftl) + adguardhome
- no sops yet (add with the service if it needs a secret)
