nuc keeps only what needs its iGPU. blocky, privoxy and transmission-bt moved to nas so the box can be powered off when not watching Jellyfin or using the Spotify kiosk. - /srv/media is now an NFSv4 mount from nas; jellyfin-server reads it with shift=false (idmapped mounts are unsupported on NFS, as the container doc already noted for CIFS) and readonly=true - replication to nas is a systemd timer with Persistent=true, not cron — an on-demand host misses its 03:30 window and cron cannot catch up Two failures documented in full, both diagnosed from the wrong layer first: - booting with the TV connected and powered on kills the i915 probe (drm_WARN_ON in intel_modeset_setup_hw_state), so /dev/dri never appears, snd_hda_intel deferred-probes forever holding the PCI device lock, and incusd blocks in sriov_numvfs_show — no container starts at all, including LAN DNS. Identical on 6.12.107 and 6.12.105. - the kiosk input gid mismatch is real but was NOT the cause of the 2026-08-30 outage (flat K400 batteries were); seatd opens input devices as root, so kiosk group membership is not on that path. Records the one-line raw capture that settles hardware-vs-software immediately. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

# Homelab: nuc
|
|
|
|
Incus host on the LAN — **on-demand**: since 2026-08-30 it only needs to
|
|
run when watching Jellyfin or using the Spotify Connect kiosk. Everything
|
|
always-on (blocky/DNS, privoxy, transmission-bt) moved to
|
|
[`nas`](../nas/README.md), which is why nuc can now be powered off.
|
|
|
|
⚠️ Powering nuc off has backup consequences — its 03:30 replication to
|
|
nas only runs while it is up. See [nas-install.md](../nas/nas-install.md) §9.
|
|
|
|
- Debian 13, Intel Alder Lake-N (iGPU `i915`, shared by both Jellyfin containers) —
|
|
bare-metal reinstall: [nuc-install.md](nuc-install.md)
|
|
- Instances are bridged onto the LAN (192.168.0.0/24)
|
|
- Storage: ZFS pool `data` on the SSD (all instance disks). The USB
|
|
4 TB and its pool **left nuc on 2026-08-30** — the enclosure's JMicron
|
|
bridge was suspending the pool ([usb4t-dropouts.md](usb4t-dropouts.md));
|
|
the disk now sits on direct SATA in [`nas`](../nas/nas-install.md) as
|
|
pool `tank`.
|
|
- Media library: `/srv/media` is now an **NFSv4 mount from nas**
|
|
(`192.168.0.4:/media`, read-only). `jellyfin-server` stays here for
|
|
the iGPU and reads it with `shift=false`
|
|
([jellyfin-server.md](jellyfin-server.md)).
|
|
- Backups: nuc and nas **cross-replicate** — nuc pushes all its
|
|
instances to `nas:nucbackup` at 03:30, nas pushes its own to
|
|
`nuc:nasbackup` at 04:00, so neither host's instances depend on that
|
|
host surviving ([nas/nas-install.md](../nas/nas-install.md) §9).
|
|
The ks4 pull leg moved to nas as well
|
|
([ks2/nas-seed.md](../ks2/nas-seed.md)), so nuc no longer runs a
|
|
WireGuard tunnel.
|
|
|
|
- ⚠️ **Never reboot nuc with the display powered on** — the i915 probe
|
|
dies and takes every container with it (including LAN DNS). Symptoms
|
|
and fix: [jellyfin-client.md](jellyfin-client.md#-never-boot-nuc-with-the-display-active-2026-08-30)

## Instances
|
|
|
|
| Name | IP | Doc | Features |
|
|
|---|---|---|---|
|
|
| [jellyfin-server](jellyfin-server.md) | 192.168.0.5 | ✅ | unprivileged, autostart; iGPU render node (`gpu` device, render gid) for QSV/VAAPI transcoding; `/srv/media` disk device (NFS from nas, `shift=false`, read-only); proxy device → host :8096 |
|
|
| [jellyfin-client](jellyfin-client.md) | 192.168.0.6 | ✅ | **privileged**, autostart; full iGPU (`gpu` device, gid 44) → HDMI kiosk (cage + Jellyfin Media Player); custom `raw.lxc` (bind `/dev/snd`, `/dev/input`, host `/run/udev`); Pioneer USB audio as ALSA default; FR keymap; go-librespot Spotify Connect ("Pioneer A-70") |
|
|
| homeassistant | (stopped) | — | **virtual machine**, 50 GiB root disk on pool `data` |
|
|
|
|
Moved to [`nas`](../nas/README.md) on 2026-08-30: `transmission-bt`
|
|
(next to the media dataset it writes to), plus `blocky` and `privoxy`
|
|
so LAN DNS and the proxy survive nuc being shut down.
