Let me explain this a little better. I know that I shouldn't need to edit 
edit /etc/defaults/rc.conf because /etc/rc.conf overrides the default. My 
question is should this be added into the CVS tree so people don't run into 
this problem while putting an 'nfs4' in /etc/fstab. If I were to have this in 
my /etc/fstab:

nfstestclient-1# cat /etc/fstab
# Device                Mountpoint      FStype  Options         Dump    Pass#
/dev/ad0s1b             none            swap    sw              0       0
/dev/ad0s1a             /               ufs     rw              1       1
/dev/ad0s1e             /tmp            ufs     rw              2       2
/dev/ad0s1f             /usr            ufs     rw              2       2
/dev/ad0s1d             /var            ufs     rw              2       2
/dev/acd0               /cdrom          cd9660  ro,noauto       0       0

10.10.10.252:/vol/vol1 /vol/vol1 nfs4 rw,noatime,-s,-i,-b 0 0
nfstestclient-1#

and I reboot the box, during bootup, my machine would errorout:

...dmesg...

nfs4: /vol/vol1: Can't assign requested address
Mounting /etc/fstab filesystems failed,  startup aborted

This is due to the fact that the system is trying to mount the NFSv4 
filesystem before the network stack is up (as per /etc/rc.d/mountcritlocal). 
If NFSv4 is stable code under the 5.3-tree, then it may be wise to add 'nfs4' 
to '/etc/defaults/rc.conf' under the 'netfs_types' option. Now I'm not 
exactly sure if NFSv4 client support is fully stable because I believe it 
might be issuing a MNT_IGNORE flag, I'll look at the source to verify.

If I add: extra_netfs_types="nfs4", the system boots up happily and I can see 
the filesystem is mounted:

nfstestclient-1# mount
/dev/ad0s1a on / (ufs, local)
devfs on /dev (devfs, local)
/dev/ad0s1e on /tmp (ufs, local, soft-updates)
/dev/ad0s1f on /usr (ufs, local, soft-updates)
/dev/ad0s1d on /var (ufs, local, soft-updates)
10.10.10.252:/vol/vol1 on /vol/vol1 (nfs4, noatime)
nfstestclient-1#

Thanks,
