The logrotate config added with the Sophie overhaul claimed to bound PZ's own logs. It did not. data/Logs had reached 18 GB across 112 entries and 146k files, and rotation had never once fired there. Two reasons, both wrong assumptions on my part. PZ rolls its logs into dated directories -- logs_2025-12-14/ through logs_2026-08-26/, up to 279 MB each -- so the Logs/*.txt glob only ever matched a handful of loose files at the top. And it rotates by size: not one file in that tree exceeds 100M, because the growth is in the number of files, not the size of any of them. Age-based pruning is the right tool, so this adds a daily zomboid-log-prune timer keeping 14 days and deleting the emptied directories behind it. It runs under podman unshare, since the files belong to the container's UID. logrotate keeps server-console.txt, which is a single ever-growing file and genuinely is what it is good at. Narrowed its scope to say so rather than implying coverage it never had. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
