Disconnected my drives, except for system root, then du is not found
mach_1# whereis du

could have done a 'umount' but results would have been the same, so I think.

Did a backup (dump) of /, file produced in 400Mb range

dump -0Lauf /disk03/dump/root2.dump /dev/ad0s1a

dumpfile size

To my surprise rootrestore-0.lst contains a whole listings of ./usr/ files
ex.

Now /usr is on a separate and distinct partition
