superuser
Permits all rug commands except user management and settings, which must be
done locally.
To give a user permission to update the system, use the command rug ua
username upgrade. Replace username with the name of the user. To revoke the
privileges of a user, use command rug ud username. To list users with their rights,
use rug ul.
To change the current privileges of a user, use rug ue username. Replace username
with name of the desired user. The edit command is interactive. It lists privileges of the
selected user and the offers you a prompt. Enter the plus (+) or minus (-) symbol and
the name of the privilege then press Enter . For example, to permit the user to delete
software, enter +remove. To save and quit, press Enter on a blank line.
2.12.2 Scheduling Updates
Using rug, the system can be updated automatically, for example, with scripts. The
simplest example is the fully automatic update. To do this, as root configure a cron
job 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 installed automatically. Instead, you may want
to retrieve the patches and select the patches for installation at a later time. To download
patches only, use the command rug up -dy. 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/redcarpet.
2.12.3 Configuring rug
rug comes with many preferences to provide the update functionality in different network
configurations. To list the preferences that may be set, use rug get. To set a preference
variable, enter rug set. For example, adjust settings if you need to update your system,
but the computer is behind a proxy server. Before downloading updates, send your
username and password to the proxy server. To do so, use the commands:
rug set proxy-url url_path
rug set proxy-username name
rug set proxy-password password
