(the first in what will undoubtedly be many questions in order to help me write my doc.) is there any way (or rationale) to distinguish between repositories listed in /etc/yum.conf? let me explain. if, as a regular user, i run "yum list", this will (AFAICT) list for me all packages available from *all* listed repositories in my /etc/yum.conf ("available" appearing to mean all packages that are either newer than installed packages or are packages not installed at all on my system, right?) can i restrict my list to just those from a selected subset of those repositories? i may have different repositories for different reasons. one repository could, for instance, be strictly for multimedia apps. or i could pick on, say, matthias' freshrpms repository just to see what's new(er) there. can i restrict my output of "yum list" in that way? it doesn't seem so from the man page, but perhaps i missed something. and this might be related to the "group" feature of yum of which i have no idea, and which is not documented in the man page. rday
