Posible to recover data, use /dev/urandom.

I did have RH Linux die while updating core libs a very long time ago. It deleted them and the system shut down. No reboot possible. I eventually (like later that day) copied a set of libs from another rh system and was able to boot and recover.

Never used rh by choice again after that.
