Both hosts were powered off and brought back from a cold start, which is
the first real test of everything built on 2026-08-30.
nas: both pools imported from /etc/zfs/zpool.cache, all instances
autostarted, NFS exports republished, 0 failed units. nuc: /dev/dri
present with 0 i915 warnings (booted with the display unplugged), NFS
auto-remounted, VAAPI transcode at 9.5x realtime.
Records the ordering that actually cleared tank's inherited
<metadata>:<0x0> and <0x3d>: a scrub alone found 0 errors and repaired 0B
but left them, and a plain `zpool clear` afterwards did not drop them —
ZFS flushes the persistent error log on a scrub run *after* the clear.
That matters beyond tidiness, because while those entries stand
`zpool status -x` reports the pool unhealthy forever and zpool-health.sh
cannot signal anything new.
Two kiosk corrections, both from observed behaviour:
- the Pioneer DAC being switched off is the most likely cause of
"video, no sound" — asound.conf pins the ALSA default to it by card
name, so `default` fails to open outright and mpv falls back to null
silently. Adds the one-line aplay check.
- hotplugging the display makes cage exit once and Restart=on-failure
recovers it ~5s later. Do NOT restart it by hand; check
ActiveEnterTimestamp against the hotplug time first.
Also flags that the OS mirror is still untested with a disk physically
unplugged — it is a guess until then.

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.

Add udev rule + oneshot service + script on nuc that restart the
container kiosk when the Logitech Unifying receiver is replugged, since
hotplug uevents don't cross into the container's netns and cage only
enumerates input at startup.

Applied live to the 5 running containers; install scripts and the
post-install checklist now include the timedatectl step.

README with instance tables and nuc<->ks4 network flow chart;
per-container install/troubleshooting docs for nuc (jellyfin
server/client, transmission-bt, bare-metal reinstall) and the
ks4 two-leg backup scheme (incus-copy over wireguard).
