I just had some fun with this yesterday using Centos 4 as the nfs server
and an FC3 client.

Using hostnames it played nice, but with ip addresses I had permissions
issues.
I am not using fstab although from this post it down not appear to be
client side issue.

tcpdump/ethereal can be most revealing in these cases as well as
debugging.

My server is using SELINUXTYPE=targeted, not sure if that really
matters, still getting my feet wet with selinux.
