A number of users have reported that running "rm --no-preserve-root -rf /" not only deletes all their files (as expected), but also permanently bricks their computers (which is not). Tracing the issue revealed that the ultimate cause was that SystemD mounted the EFI pseudo-fs as read-write even when this FS was not listed in fstab, and deleting certain files in this pseudo-fs causes certain buggy, but very common, firmware not to POST anymore. A user reported this bug on SystemD's GitHub issue tracker, asking that the FS be mounted read-only instead of read-write, and said bug was immediately closed as invalid. The comment thread for the bug was locked shortly after. Discuss.

Sorry, but theres *LOTS* of buggy hardware out there. When software is designed to run on that hardware it is *expected* to compensate for those bugs.
Yes, it's a hardware bug. It's **ALSO** a software bug.
Javascript is what you use to allow unknown third parties to run software you have no idea about on your computer.
