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).

    Well I, for one, am shocked that OP is throwing a tantrum like a little bitch instead of following through its loudly proclaimed threats to leave.

    I would say to not let the door hit you on the way out (not out of any concern for your well being, mind you, but more of an "avoid spreading AIDs in the common area" courtesy to the other visitors), but we both know that you never had any intention of actually leaving.
