A host-side daily job creates the next day's dated log files as root:root at 00:00 UTC; LibreChat (cloudron user) then EACCES-crashes on its first log write of the day (2026-10-22 and 2026-10-23 incidents). The guard pre-creates today's and tomorrow's files as cloudron and repairs strays every minute. Defense-in-depth until the host rotation config is fixed.

# A host-side daily job creates the next day's dated log files
|
|
# (error-<date>.log, meiliSync-<date>.log, ...) as root:root at 00:00 UTC.
|
|
# LibreChat runs as the `cloudron` user and crashes (EACCES on uncaught
|
|
# error) the first time it tries to append to a root-owned log. This guard
|
|
# runs as root (via supervisord) and, every minute:
|
|
# 1. pre-creates TODAY's and TOMORROW's dated files owned by cloudron
|
|
# (an existing correctly-owned file defeats the ownership flip —
|
|
# open(O_TRUNC) preserves the inode's owner),
|
|
# 2. chowns any root-owned strays back to cloudron.
|
|
#
|
|
# This is a defense-in-depth stopgap; the host-side rotation config should
|
|
# still be fixed to create files as cloudron (see co-op/support thread and
|
|
# the overlay README).
