You just have to keep the account ID synced when you create them, which is usually quite easy, but does require you to be aware of the need to do it. Even more of an issue once you start dealing with NFS. As Patrick O'Callaghan says then you start thinking about LDAP etc., but it's a pain to set up and doesn't address the situation of multi-boot systems (though that's a small number). In theory installers could check this stuff and offer to synchronise uids for you (GIDs might be a bit more of a problem since lower ones are often used for system things, room for some standardisation there if it hasn't already happened, but those things tend to be restricted to /etc and other directories that wouldn't be shared anyway). I wonder if there are similar problems with Selinux contexts or if those are standardised enough to start with (and, again, the funny ones will probably not be in directories shared between systems). -- imalone -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
