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...

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,
