Don't do this. If you need to do a full restore of / do it by booting
from some alternate location (media, net, another disk), mounting the
appropriate device, and then restoring onto it.

--tim

I forget if there's a `just clobber everything' option to ufsrestore.
The typical case you're doing a full restore like this is when you've
lost disk with / on so it probably is a moot point. (Remember in that
case to install the boot blocks, otherwise the machine will not boot.)
