Bug#904079: systemd: tmpfiles: cleaning up /tmp at boot breaks things

[Arnaud Rebillout]

Package: systemd
Version: 239-5
Severity: normal

Dear Maintainer,

At the moment Debian carries a patch against /usr/lib/tmpfiles.d/tmp.conf
This patch sets the type for `/tmp` to `D`, causing the content of the
directory to be removed when systemd-tmpfiles is invoked with `--remove`.
See man tmpfiles.d(5) and man systemd-tmpfiles(8).

In other words, `/tmp` is cleaned up at some moment of the boot, and
there's a risk that a process is owning and using a file at this moment,
causing a failure.

I personally came accross such failure with console-setup, and the bug
is already reported at:
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=846256>

It seems to me that just dropping the patch would solve the issue.

This patch was introduced after this discussion:
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=675422>

The discussion doesn't actually give much rational about the patch.

Thanks,

  Arnaud
