The biggest problem is when you have / and /usr and/or /var split over multiple
fielsystems.  Singel user boot (w/ -r) will work, but you can't mount
any filesystems because the device tree is shot.  You can't regenerate the
device tree unless you can mount /usr (and you may require /var also)

echo '#path_to_inst_bootstrap_1" > /etc/path_to_inst

followed by a "boot -r" may get you somewhere;
but if you can't mount /usr, you're toast.
