I guess you are using 5.3 or newer? the /etc/rc.d/diskless script has been replaced, by among other things, a script /etc/rc.d/var which creates a memory disk, /dev/md0, using up your precious ram. I have tried to remove the script but get an error because nfs wants to update the /var/db/mounttab - before /var is actually mounted - so the mount fails. The /etc/rc.d/var script creates a memory disk if it detects that /var is read-only - which is the case since the nfs mount failed. And the memory disk is then populated. If the root partition is rw-mounted the nfs-mount will succeed. If you have enough ram this is not a problem, simply let var be a memory disk. You can set the size of the memory disk in rc.conf. > /dev/md0 on /var (ufs, local, soft-updates) > 192.168.122.1:/pool/diskless_rw/192.168.122.11/var on /var (nfs) Now this is wierd - how can you have to mounts on the same mount point?
