  Fsck deleted /etc/passwd on boot of my 3b2.  It now will not let
anyone login.  Is there anything else that can be done besides reload
unix?  I can get to the firmware monitor.  Optimally, I'd like some
sort of diskzap program that can run standalone, or some way of
trashing /etc/inittab so it will boot in single user.
