8.14.5 Scheduling Updates
Using rug, the system can be updated automatically (for example, by scripts). The
simplest example is a fully automatic update. To do this, configure a cron job as root
that executes rug up -y. The up -y option downloads and installs the patches from
your catalogs without confirmation.
