Great! Any tools available to extract my var/db/pkg dirs from this image
of my trashed UFS2 filesystem? :>
What seems to work is to boot from CD-ROM, use
disklabel -r -w <disk> auto
to reinstall the default disklabel, then
disklabel -B <disk>
to put back the bootstrap. At that point your existing filesystems
should all come back. This of course assumes that you used the
orginal default partition sizes. If not, you will need to
figure them out and edit up an appropriate disk label.
