Where does the up2date in Fedora Core 3 sit in this?

Does it get source too? That's about third on the list of things I like 
to do.

I really don't like the mirror list I've seen in Fedora Core. It pulls 
stuff from all over, Europe, Middle East - mostly, it seems, about as 
far away from Western Australia as possible.

I prefer the Debian approach; I choose a mirror. In Australia, IAPs 
commonly have a peering arrangement; content from within the peer 
network isn't charge against download limits. While (AFAIK) all members 
of WAIX (the local peer network) are in WA, not all IAPs in WA are members.

I've never used yumex, do I can't tell whether up2date's GUI capability 
is like yumex's.

As I mentioned elsewhere, installed 4.3 just before 4.4 came out. I'd 
uch rather have downloaded the packages overnight (triggered by cron) 
than type the commands in through my modem line.

GUIs aren't very good through modems.
