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.

    Me: GOD. I would like to report a bug.
    GOD: Yes, many bugs were created to clean up the earth.
    Me: No not that kind of bug.
    GOD: What kind of Bug are you refering to, my son?
    Me: It's named "Poettering" and it keeps breaking things and blaming others.
    GOD: Oh him. Yeah I created it. But it's just a test of your Linux community to see how well you can deal with the Devel.
    Me: You mean Devil.
    GOD: I don't make mistakes.
    Me: Oh. Sorry. I'll think more before I .... GOD? GOD? You still there? GOD?
