Another thing to consider besides the dependency calculation is the NFS
mount options. If you go to Alt-F2 and cat /proc/mounts, is your NFS
mount rsize=32768,wsize=32768,udp? If so, this could be your problem.
I recently submitted a patch to the Anaconda developers for RHEL 4
U2_beta that allows you to pass
"nfsmountopts=rsize=16384,wsize=16384,tcp" or any other NFS mount
options to loader. This helps installations where UDP and large (32K)
rsize/wsize are a bad idea.
