# Systemd template for a supervised timberfs log intake (see timberfs-log@.socket).
#
# Drains the instance's FIFO (passed as stdin by the socket unit) into a store
# at /var/log/timberfs/<instance>.log. The producer must write a
# timberfs-records(5) stream (that is what --records means); to archive a
# plain-text source instead, drop --records from ExecStart. Override the store
# path, add retention, or change the format with a drop-in:
#
# systemctl edit timberfs-log@applogs.service
# [Service]
# ExecStart=
# ExecStart=/usr/bin/timberfs append --records --into /srv/logs/applogs.log --retain 30d
#
# This is socket-activated: enable the .socket, not this unit. The first write
# starts it and Restart=always keeps it up; a restart or upgrade is invisible to
# the producer because the socket holds the FIFO open across it.
