Try chrooting in the FreeBSIE environment on the mounted device, e.g.:
mkdir /mnt/fbsd_root
mount /dev/da0s1a /mnt/fbsd_root
#mount other filesystems here--make sure that the path is relative
to /mnt/fbsd_root and follows the same sort of rules as specified in
/mnt/fbsd_root/etc/fstab!
chroot /mnt/fbsd_root /bin/tcsh # insert your shell of choice
available here.
You need to make sure that all devices are mounted properly ('/',
'/usr/', '/var', etc), and the /dev filesystems are mounted in the
chroot environment before continuing. This is basically what users do
when installing Gentoo Linux, and I don't think that you should have an
issue with it when trying to upgrade and fix your FreeBSD system because
the principle is the same. Not sure how to do the devfs filesystems, but
I'm sure someone has an idea of how it's done; IIRC it was done by the
kernel somehow.
