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.

In any case it can't be a bug because systemd has no bugs [freedesktop.org]. They've closed the Bugzilla tracker, so obviously it's reached a state of perfection where no more bugs need to be reported or fixed.

Incorrect. A different search for "systemd" on that site shows over 500 bugs outstanding, including several assigned to lennart or to systemd-bugs.

Those are all old bugs that have been ignored since last year or much earlier. You can't file new bugs on that bug tracker because it's been closed. Give it a try if you don't believe me.
