vi /config/juniper.conf and remove the root-authentication line (or
replace with your own md5crypt from a unix system), then reboot, and the
password in all of the bsd components will be rebuilt from the junos
config. Of course if fsck really fails and you can't continue, you have
much bigger problems than the password. :)
