 ### **plex32_health_report.sh — Issues List Word-Wrapping Fix (2026-07-12)**
 The "⚠ Issues Detected" block in the daily health report email was rendering each word of an issue message on its own line (e.g. "WARNING: NAS08 — Plex Config is getting full" appeared as one word per line) instead of as a single readable sentence.

 - **`plex32_update_check.sh` fixed 2026-07-12** — added explicit `PATH` export to fix intermittent `docker pull` failures under root's cron environment; script now logs real `docker pull` error output on failure instead of a generic "could not reach registry" message. All three PLEX32 scheduled jobs run under root's crontab.
 - **`plex32_update_check.sh` fixed again 2026-08-04** — added a 3-attempt retry loop (30s apart) around `docker pull` to handle `lscr.io`'s transient `error from registry: unauthorized` failure (all layers pull successfully, then the final manifest step fails — a known registry-side token/rate-limit issue, not a credentials problem). Also re-added the `PATH` export from the 2026-07-12 fix, which had gone missing from the deployed script. Only a failure across all 3 attempts is now reported as `CHECK FAILED`; a retry success is noted inline in the email instead of being silently indistinguishable from a clean pull.
 - **`plex32_health_report.sh` fixed 2026-07-12** — fixed the "Issues Detected" email block rendering each word on its own line, caused by a multi-character `IFS='. '` split; issues are now newline-delimited and read back with a `while read` loop.

+- **`plex32_update_check.sh` updated 2026-08-18** — replaced heavy `docker pull` layer downloads with `skopeo inspect` for fast manifest digest comparisons. Adjusted Step 5 logic to prioritize "Updates Available" blue banner over non-fatal script check warnings.
+- **Systemd override for Docker added 2026-08-19** — added `/etc/systemd/system/docker.service.d/override.conf` with `After=network-online.target remote-fs.target` and `Wants=network-online.target remote-fs.target` so Docker waits for NFS mounts on boot before starting containers.
