The current official guidelines are written with this in mind, see also https://fedoraproject.org/wiki/Packaging/UsersAndGroups where this is briefly discussed. E.g. maybe OLPC only needs an extended setup package (the package's name is indeed "setup") where some key uids/gids are set and thus globally the same even if Fedora as upstream may be assigning them dynamically. You would only run into trouble if Fedora ever decides to statically assign any of the uids/gids itself to a different uid/gid, which is rather unlikely. In a nutshell: the guidelines (that are not yet followed by all packages, there is always a lead-time to let a guideline sink in) ensure that you can have both dynamic assignment and a preset static one with the same package, even w/o having to rebuild the package. > Now, that practice will make OLPC packages unacceptable to Fedora > proper - this is more important to me.

Actually the long flamewars on it has led to a stale situation - fedora-usermgmt was never accepted into the Fedora canon as a packaging guideline, but also not officially banned either. But the URL I gave you above is the official vote to a guideline from the FPC, ATM it doesn't get any more official. -- Axel.Thimm at ATrpms.net
