You wouldn&#x27;t be able to run any programs from the hard drive, and when you reboot, you&#x27;ll end up with no operating system.<p>Unless you&#x27;re running FreeBSD (or Illumos) with ZFS and Boot Environments, in which case you&#x27;d just select a backup boot environment and continue working :-) Probably without your home directory though, as that is usually excluded from boot environments. But you can set them up however you want.<p>But if you&#x27;re running Linux (before this update) on a laptop with terrible piece of shit firmware, you&#x27;d end up with a brick.<p>P.S. found a cool post about rm -rf &#x2F; in my bookmarks: <a href="https:&#x2F;&#x2F;lambdaops.com&#x2F;rm-rf-remains&#x2F;" rel="nofollow">https:&#x2F;&#x2F;lambdaops.com&#x2F;rm-rf-remains&#x2F;</a> – you can recover a running rm&#x27;d Linux machine by using a running shell and &#x2F;dev&#x2F;tcp :D
