# /etc/logbackup.d/clean
#   logbackup fragment to clean unwanted logs
#
#   This script allows rotation and backup of log files,
#   on systems where /var/log is mounted as tmpfs.
#
#   It is called by /etc/init.d/logbackup:
#    - at system startup to retreive backed-up logs to /var/log
#    - on a daily basis to rotate and back-up the logs on the hard-drive
#    - at system halt or reboot to back-up the logs before the
#      tmpfs is unmounted
#
#   This script removes unwanted logs to prevent their filling the entire
#   /var/log partition.
