from the why-oh-why dept.

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.

    Poetering is not in the customer service business. He's in Poetering service business and his serfs obey that law. You have to be seriously fucked up when you let people suffer, even if it wasn't your fault (which i still argue is, in this case, partly), when you could fix it easily.
