If you have a FreeBSD CD set then boot from disk 2, then in sysinstall
choose the "Fixit" menu item. This should allow you to mount your root
partition as /mnt, and manipulate it, while using the installation mfsroot
as a temporary root filesystem.

If you don't have the CDs then you can do the same sort of thing with
boot floppies. Go to

(or some suitable mirror thereof) and fetch fixit.flp, kern.flp,
mfsroot.flp and the README file. Use the flp images to create floppies as
outlined in the README file, boot from the kern.flp disk, feed it the
mfsroot.flp disk when prompted, then choose Fixit in sysinstall and feed
it the fixit.flp disk.

Hope this helps.
