There were lots of good titles for this submission, as in "Breaking news: Poettering clueless?" to finally disprove Betteridge's law, or "systemd surprisingly not as good as advertised" or "Breaking new: systemd broken" or "Poettering censors critics after epic fail".

Systemd implementation of "rm -rf .*" will follow ".." to upper directory and erase /

How to reproduce:
        # mkdir -p /foo/dir{1,2}

        # touch /foo/.bar{1,2}

        # cat /etc/tmpfiles.d/test.conf

        R! /foo/.* - - - - -

        Reboot.

After the issue was fixed, finally Poettering added this gem of wisdom:

I am not sure I'd consider this much of a problem. Yeah, it's a UNIX pitfall, but "rm -rf /foo/.*" will work the exact same way, no?

The answer to this question, as many clarified for him, obviously is a loud "NO!". After being told a couple of times in no uncertain terms, the thread was closed for non-developers

poettering locked and limited conversation to collaborators 4 hours ago

for which I proposed the "freedom-of-speech" department (although I admit it is a weak proposal).

    My fault. I botched the sub trying to get stuff in the queue and totally missed the lack of link.

    I shall go put my hands on the fence post and await my whipping.

    I actually copy-pasta'd lennart's quote into google shortly after posting that and found it. Thanks though :D

    I think the form should require a link. For the subs and for the published stories.

    Make the robot do the work, they don't mind it.
