Caddy was rotating on implicit defaults (100MiB/keep 10/90d) that were not
holding -- 20 rotated files per stream and a 190-day-old .gz, 1.3 GB across
16 log streams. Made explicit at 10MiB/keep 3/7d.
Note roll_size et al are subdirectives of `output file`, NOT of `log`.
Getting that wrong does not degrade gracefully: Caddy refuses to start on a
bad config, so every site went down until it was corrected. Worth a
`caddy validate` gate before reload.
journald had no SystemMaxUse and had reached 4 GB, drifting toward its
10%-of-filesystem default (~190 GB on this root). Capped at 500M.
Both are safe to keep short because fluent-bit ships the journal and every
Caddy access log into Graylog -- though note its GELF output has been
erroring for days, which weakens that premise and wants investigating.
The larger find was unrelated to logs: 896 images totalling 59.6 GB with
75% unused (94 tags of greg-time-bot, 73 of fulfillr -- one per deploy) and
5.4 GB of dangling volumes, mostly 804 MB Nextcloud /var/www/html trees
orphaned by container recreations. Pruned to 22 images / 15.4 GB, and added
a weekly timer keeping 30 days so a rollback still needs no rebuild.
Also dropped the decommissioned 6379/tcp redis rule (nothing listening;
Immich's redis is on the shared podman network) and the orphaned nosql, s3
and searxng volume dirs.
Backup log exclusions turned out to be unnecessary: Gitea logs to console
so its log dirs are empty, Nextcloud already excludes its own, BookStack
mounts only uploads, and Caddy is not backed up.

The data-only rsync left no way to restore a working instance: mysql/ and
config/ were never backed up, so a recovery would have files but no shares,
users or metadata. Dump the database before syncing files (a DB older than
the files is repairable with occ files:scan; a newer one references blobs
that never made it into the backup) and ship config/ alongside it.
Capture the --chmod=Du=rwx,Dgo=rx flag that had been hand-added to the
deployed skudak-cloud script. It was outside git, so every deploy silently
reverted it. It now lives in backup_rsync_extra_args.
Add OnFailure= alerting. The units failed silently before, which is how an
iDrive sync failure sat unnoticed since May. msmtp rather than the esmtp
already installed: the OpenSRS relay is port 465 (implicit TLS) and libesmtp
only speaks STARTTLS.
Exclude nextcloud.log* from the sync and cap log_rotate_size. skudak-cloud
was running at loglevel 0 and had written a 64 GB log that was being rsynced
and pushed to S3; set it to 2 to match the home instance.
Stagger the timers (04:00 / 04:30) so both finish before the 05:00 TrueNAS
snapshot task, and bound TimeoutStartSec so a wedged rsync cannot leave the
unit activating forever and skip every subsequent trigger.

- Move fluent-bit to common role (systemd service, not a container)
- Move geoip to podman/tasks/data/ (data prep, not a container)
- Remove debyltech tag from geoip (not a debyltech service)
- Fix check_mode for fetch subuid task to enable dry-run mode
