Hi Jim,
I tried, the same, but now a different error. My /etc/exports ,look
like this
# /etc/exports: the access control list for filesystems which may be
exported
# to NFS clients. See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes hostname1(rw,sync,no_subtree_check)
hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check)
#
/nfs/gen1
192.168.0.0/255.255.255.0(rw,no_root_squash,insecure,no_subtree_check)
My /etc/fstab looks like this
proc /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs default 0 0

Ok I've had another thought.
What are your nfs export options in your /etc/exports file on your nfs
server?
Mine are
/home/export/debdev sc(rw,no_root_squash,insecure,no_subtree_check)
"sc" is the name of my board in my /etc/hosts file. The no_root_squash
option is important.
