# A dedicated shutdown service is used to write the offset file instead
# of using the stop function of the swclock-offset service at boot. This
# approach is more fail-safe on different installation/deinstallation
# situations.
#
# Because the shutdown services are performed late within the shutdown
# runlevel, dependencies are needed to execute the script before
# processes are killed and filesystems are remounted read-only.
