9.1.5 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.
However, you may not want the patches to be installed automatically, but may want to
retrieve them and select the patches for installation at a later time. To download patches
only, use the rug up -dy command. The up -dy option downloads the patches
from your catalogs without confirmation and saves them to the rug cache. The default
location of the rug cache is /var/cache/zmd.
9.1.6 Configuring rug
rug allows you to customize its setup via a set of preferences. Some of them are pre-
configured during installation. Use rug get command to get a list of the preferences
available. To edit a preference, enter rug set preference. For example, adjust
settings if you need to update your system through a proxy. Before downloading the
updates, send your username and password to the proxy server. To do so, use the fol-
lowing commands:
rug set proxy-url url_path
rug set proxy-username name
rug set proxy-password password
Replace url_path by the name of your proxy server. Replace name by your username.
Replace password by your password.
