Doesn't  work here.  This is NOT a new setup.  I am testing this with an 
existing environment that has been working for years.  I have various Linux 
boxes, Solaris, etc.  All of them hang forever trying to mount this updated 
server.

On the FC2T2 server:

selinux=0
>mount
/dev/mapper/Volume01-LogVol00 on / type ext3 (rw,acl)
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
usbdevfs on /proc/bus/usb type usbdevfs (rw)
/dev/hde1 on /boot type ext3 (rw)
none on /dev/shm type tmpfs (rw)
none on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
none on /proc/fs/nfsd type nfsd (rw)
automount(pid1665) on /net type 
autofs(rw,fd=4,pgrp=1665,minproto=2,maxproto=4)
automount(pid1716) on /user type autofs 
(rw,fd=4,pgrp=1716,minproto=2,maxproto=4)
automount(pid1726) on /home type autofs 
(rw,fd=4,pgrp=1726,minproto=2,maxproto=4)
/disk1/nbecker on /home/nbecker type none (rw,bind)

For example, here is one client:
uname -a
SunOS vlsisun21 5.8 Generic_108528-18 sun4u sparc

Another example, I'm trying to boot FC2T2 on another linux box using NFS 
install.  Both hang forever. 

Here's what the server says:
