# This is a helper script for update-f123light to perform incremental updates based on a timestamp
# It will not be installed to a running system
#
# Incremental updates are only to be performed if their timestamp is later than
# /etc/timestamp-f123light on the system being updated.
# Each update should be formatted as
#
# update yymmddhhmm && {
# 	do-something here;
# 	do-something-else here;
# }
# If an update requires a reboot, add
# reboot=true
# anywhere in the update to prompt the user to reboot afterward
#
# Any new updates should be placed at the end of this file for best readability
# It is recommended to skip a line between updates, also for readability
# To get the current date and time in the format, use the command
# \date '+%y%m%d%H%M'
# Remember to add a ; after each line of the update group.
