yum now uses its own depsolver instead of rpmlib which is slower. I know that its planned to make it working first befor starting to optimize it.
Is it possible to turn it off and use the old one? It just cancelled it after
it had been running for four hours, hoping I'll be able to use the old one,
because this is just ridiculous. I wonder how apt-get does it, it's able to
give me the list of updated/installed/whatever packages in less than a minute
on a 32MB RAM Celeron 233MHz box and yum needs more than 4 hours on 256MB RAM
vmware on dualcore Pentium on 3Ghz?


I'm getting a little annoyed at this conversation.

Apparently it is not acceptable for things to be not-working or
less-good in rawhide. Apparently, we have to go from one working state
to another perfectly working state w/o passing through any situation in
which it is not as functional.

We told everyone up front that what is going on right now is slower and
larger while we work on getting it right and yet that doesn't seem to
stop the useless bitching and moaning w/o any offers of help at all.

IMHO, this discussion brings into sharp relief just how good Rawhide really is. It's so good that I've become accustomed to near release quality software at any and all points in the Rawhide life cycle. Occasionally something breaks -- spectacularly, even -- but it often gets fixed within a few days. This yum-in-transition performance issue is just another bump in an otherwise pretty darned smooth road, all things considered, and I'd argue that if Rawhide were more unstable, the instant yum issue wouldn't seem nearly so contemptible.

I like running the latest stuff. I like Rawhide. I like Fedora. You guys are doing a great job.

An alternate voice from a satisfied Rawhide user/tester,
Jay
