9.1.4 rug User Management
One the main advantages of rug is its user management. Normally, only root can
update or install new packages. With rug, you can assign the right to update the system
to other users and restrict them, for example, to only updating without the possibility
to remove software. Privileges you can grant are:
install
The user may install new software
lock
The user may set package locks
remove
The user may remove software
subscribe
The user may change channel subscriptions
trusted
The user is considered as trusted, so he is able to install packages without package
signatures
upgrade
The user may update software packages
view
This allows the user to see which software is installed on the machine and which
software is in available channels. The option is relevant only to remote users. Local
users are normally permitted to view installed and available packages.
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 rug ua username upgrade
command. Replace username by 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.
