What command line arguments are you passing to anaconda, and can you attach
/tmp/anaconda.log to this bug report?

boot command line contains...

--loglevel=debug ksdev=bootif noipv6 repo=nfs:gelk:/mnt/data/mirror/rawhide/x86_64/

log to follow..

ah. this one is my fault. (though it's arguable that anaconda shouldn't
traceback, but show an error dialog instead)

In my original tests, my pxe boot command line had..

repo=nfs:gelk:/mnt/data/mirror/rawhide/x86_64/os/

this fails to get stage2, but pops up a dialog asking for the path. I deleted
the os/ part of the string, and it went on its merry way.  until it crashes with
the traceback.

pxebooting todays tree with a correct repo path works just fine.

I'll attach the log for the pathological case anyway in case you feel that
anaconda needs to be hardened against use by stupid people.

Working on the hardening right now, in fact...

Okay, this should be fixed up in the next build of anaconda.
