I've got all this working with your help but I still have to mount the 
server manually. Fstab contains the following lines:

    [root at box7 bobg]# cat /etc/fstab
    #
    # /etc/fstab
    # Created by anaconda on Tue Aug  7 08:37:16 2012
    #
    # Accessible filesystems, by reference, are maintained under '/dev/disk'
    # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for
    more info
    #
    UUID=4ce86523-2d45-4174-85e9-fd298e4516c8 / ext4    defaults        1 1
    UUID=1a9d0937-2247-4cbc-b27d-4775c7453dba /boot ext4   
    defaults        1 2
    UUID=96a666e2-73ac-4f5f-98bc-4a6a9383491f /home ext4   
    defaults        1 2
    UUID=9cb5a7e0-c752-4563-b7f5-663980e090e3 swap swap   
    defaults        0 0


    192.168.1.8:/nfs4exports/     /mnt/BOX8     nfs4     rw,bind 0 0
    192.168.1.8:/home/   /mnt/HOME1/     nfs4    rw,bind  0 0
    192.168.1.8:/data/   /mnt/DATA1      nfs4    rw,bind  0 0
    192.168.1.48:/SRVR1              /mnt/BOX48      nfs4
    defaults,rw,user 0 0

The server box48 mounts during the boot process, box8 does not. I see 
the following lines in "mount":

    /dev/sdb3 on /mnt/BOX8 type ext4 (rw,relatime,seclabel,data=ordered)
    /dev/sdb3 on /mnt/HOME1 type ext4 (rw,relatime,seclabel,data=ordered)
    /dev/sdb3 on /mnt/DATA1 type ext4 (rw,relatime,seclabel,data=ordered)
    192.168.1.48://SRVR1 on /mnt/BOX48 type nfs4
    (rw,nosuid,nodev,noexec,relatime,vers=4.0,rsize=262144,wsize=262144,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=192.168.1.7,local_lock=none,addr=192.168.1.48)
    gvfs-fuse-daemon on /run/user/bobg/gvfs type fuse.gvfs-fuse-daemon
    (rw,nosuid,nodev,relatime,user_id=1000,group_id=1000)

Which raises the question why are the non-working mounts shown as 
/dev/sdbx while the one that mounts [box48] does not? Then after 
mounting manually with "[root at box7 bobg]# mount 192.168.1.8:/home/   
/mnt/HOME1/" mount shows:

    192.168.1.8:/home on /mnt/HOME1 type nfs4
    (rw,relatime,vers=4.0,rsize=524288,wsize=524288,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=192.168.1.7,local_lock=none,addr=192.168.1.8)

Any thoughts? I am getting nowhere on it.

Bob
