NFS Under Redhat 6.0?

[Bret Orsburn]

This must be a FAQ, but I've groped & grep'd all over the Net without finding
any useful info, so here's my plight:

Under Redhat 5.x, NFS "just worked".

Under Redhat 6.0, all of our SunOS NFS clients have to mount their
Redhat-6.0-exported directories with the "-o vers=2" option.

Why is this? What can we do about it?

TIA.
