## Summary
Verified the UOS Server (self-hosted UniFi OS Server, `172.16.3.29`) was up to date, then
patched the host OS on request.

- **UniFi layer (already current):** UniFi OS Server **5.1.19** / UniFi Network **10.4.57** —
  the newest published builds (5.1.19 released 2026-06-18). The in-guest `uosserver-updater.service`
  is working; it auto-stepped 5.1.15 -> 5.1.19 on 2026-06-21. App runs in the rootless podman
  container `uosserver`; container reported Up (healthy).
- **Host OS (was behind):** Rocky Linux **9.1** -> **9.8**. `dnf -y update` applied **362 packages**
  (full security backlog), incl. new kernel `5.14.0-162.6.1.el9_1` -> `5.14.0-687.17.1.el9_8`.
  Clean reboot (~24s back to SSH, ~4 min to container healthy). Controller web UI HTTP 200,
  `uosserver status` healthy post-reboot. Old kernel retained as fallback boot entry.

## Access used
- SSH root via vaulted fleet key `infrastructure/uos-server-ssh-key`
  (field `credentials.ssh-private-key-b64`, base64-decoded to a temp key, removed after).

## Commands (key)
- `dnf -q check-update | wc -l` (362), `dnf -q updateinfo list security`, `dnf check-update kernel`
- `dnf -y update` ; `systemctl reboot`
- Verify: `uosserver status` (container Up healthy), `uosserver version` (5.1.19),
  `curl -sk -o /dev/null -w "%{http_code}" https://127.0.0.1:11443/` (200)

## Files changed
- `wiki/systems/uos-server.md` — guest line updated to Rocky 9.8 + kernel; new
  "Host OS maintenance (Rocky)" section (procedure, safety-net autobackup path, reboot impact,
  history line); frontmatter `last_compiled: 2026-06-26`.

## Notes / follow-ups
- Host OS is NOT auto-patched (only the UniFi container self-updates) — patch manually on a
  cadence. Daily UniFi autobackups exist at
  `~uosserver/.local/share/containers/storage/volumes/uosserver_var_lib_unifi/_data/backup/autobackup/`.
- No VM snapshot taken (user opted to proceed on autobackup only); update was clean.
