Optional: run every 6 hours via cron

By default `slk-changelog-check` runs once at boot from `rc.local`.
If you want it to also check every 6 hours, add a cron job as root:


# su -
# crontab -e


Add this line:


0 */6 * * * /usr/bin/slk-changelog-check


Save and exit. Verify it was added:

crontab -l


You can watch behavior from `/var/log/messages` something like this:

cat /var/log/messages | grep slk
