Bug#1018872: systemd.service COMMAND LINE misses command search, if starting with "+".

[Harald Bergmann]

Package: systemd
Version: 247.3-7
Severity: minor

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
Implementing some systemd.service, which requires preparation by ExecStartPre.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Added: ExecStartPre=+mkdir -p <folder> ; +chown -R <user>:<group> <folder>

   * What was the outcome of this action?
Result via service start and via analysing (sudo systemd-analyze verify
<service>):
Command mkdir is not executable: Datei oder Verzeichnis nicht gefunden

   * What outcome did you expect instead?
Execution without error message.

*** End of the template - remove these template lines ***

Workaround using a little different COMMAND LINE:
ExecStartPre=+/bin/mkdir -p <folder> ; +chown -R <user>:<group> <folder

Identified problem:
The command is not found at the standard paths. This happens only, if the
command is prefixed with "+" or (likely) any other possible prefix character,
which "man systemd.service" tells (not tested).

Because the workaround is easy, the bug is classified as minor.
