No a huge ammount of help, but my FC2 ccrma box at home mounts its /home
off an NFS server and it works fine. I was thinking of taking it to FC3,
but maybe I'l wait :)
Have you set the sync flag on your NFS server? e.g.
/home 10.11.12.*(rw,sync)
I think this is important in recent kernels, but I cant remember why.
