1. Have you looked into /lost+found ?

2. You could try to grep the raw device of the root partition,
searching for known fragments of the old /etc/rc.conf,
and then manually recreate it. But do this fast, before
the now freed blocks are reused and thus overwritten
again. You do have a small separate / partition, right?
Better run the system with / mounted read-only, until
you can find the deleted fragments.
