This indicates a severe error, as you have correctly observed.
Step 1 is to make / writeable:
# mount -u /
which is a "shortcut" for
# mount -u -o rw /
You will also need to mount partitions like /usr to make your
normal editor working (for example /usr/bin/ee):
# mount /usr
or even
# mount -a
In case this step is not _possible_, you can still use an editor
present on / (typically /rescue/vi):
# /rescue/vi /etc/rc.conf
Apply the quotes as required and :wq (write file and quit the
editor). Then you should be able to let the system reboot normally.
