XS specific notes on how to build RPM packages (see also XS Directory Layout).
 Users and Groups
When creating new users / groups, we follow the policy and code style as set forth in http://fedoraproject.org/wiki/Packaging/UsersAndGroups
Hint: In the above link, read carefully around the mention of a "setup" package.
To create static uids/gids for XS boxes, we will provide a custom setup package. More documentation to follow...
