Without ContainerName= the v1 generator names the container
systemd-tautulli; the fleet references containers by their plain names
(podman inspect/exec, deployer health checks). Container was healthy but
renamed — caught by post-cutover verification, not by the seam; the seam
only asserts file keys, so pin the name here and keep plex/tautulli
structures parallel.
- tautulli.container: HealthCmd switches to the repo's proven curl pattern
(jellyfin unit) — quadlet's systemd-style value parsing mangles embedded
double quotes; PublishPort=8181:8181 restored (a mis-aimed line edit
replaced it; the PublishPort seam test caught the regression)
- deploy_plex readiness gate: 36x5s -> 120x5s; the 2026-09 cutover showed
the first container boot of a years-old library runs ~10 min while PMS
pre-binds 32400 and empty-replies; 180s failed the gate twice with a
healthy, still-booting service
Evidence from the failed first cutover: podman top shows container root
maps to dank (1000) under UserNS=host rootless (subuid range 100000:65536
cannot express 997), so PUID=997 fell back to root and PMS crash-looped on
write access to its 997:984-owned data root. Fleet model instead: PUID=0/
PGID=0 (container root = dank, same as jellyfin/copyparty data roots) and
deploy_plex chowns /var/lib/plexmediaserver to 1000:1000 inside the
first-cutover block. Zero bytes moved; rollback regains one chown -R
997:984 step, documented in Plex.md. Seam test pins PUID=0/PGID=0 and the
absence of any userns key.
podman 5.7 podman-user-generator on dankserver hard-fails the whole unit on
the unknown key ('unsupported key UsernsMode in group Container'), so the
first cutover attempt masked the native unit and then found no plex.service
at all. Swap both units to UserNS=host (same --userns=host flag), update the
ownership-contract seam test to pin the exact key, and correct both docs.
Pin the seam: the v1 generator rejects unknown Container keys silently at
deploy distance — the test now pins UserNS=, not the misspelled alias.
- plex: lscr.io/linuxserver/plex:1.43.3.10896-cb3ebc72d-ls322 (verified ==
ghcr latest digest; plan's ls9 pin superseded by the re-verify clause),
/var/lib/plexmediaserver bind-mounted in place as /config, /mnt/entropy
mounted ro at the same path, PUID=997/PGID=984 + UsernsMode=host so the
container's file identity is byte-compatible with the native unit
- tautulli: lscr.io/linuxserver/tautulli:v2.18.1-ls242 (verified == ghcr
latest digest), fresh /home/dank/Containers/tautulli config root,
PUID=1000/PGID=1000, python3 /home healthcheck
- both on dankserver_appnet with aliases; 32400/8181 published as before
