Re: dependency resolution ?

actually, it's more the 270000.

but the up2date client only requests the package that provides a certain
dependency, so the server's decision is simple - find what provides it and
return to the client. you don't have to do circular resolution - so it
doesn't look so hard. and conflicts are detected by the up2date client, so
the server doesn't have to think about them. I will have to look into
onsoletes though - didn't have the time to look that up - i know redhat put
an additional obsoletes list in the 3.0 version ;(

it is interesting though what to do if several packages provide the same
capability, like the xfree86 server - there is about 20 packages for
different video cards, all of them provide "Xserver"- i wonder what to do
then.
