[Pkg-utopia-maintainers] Bug#979791: pipewire: started automatically with root SSH connections

[Laurent Bonnaud]

Package: pipewire
Version: 0.3.15-1
Severity: normal


Dear Maintainer,

    * What led up to the situation?

I log in with SSH to the root account of a system where pipewire is installed.

    * What was the outcome of this action?

A pipewire process is started automatically by systemd:

# systemd-cgls
Control group /:
-.slice
├─user.slice
│ └─user-0.slice
[...]
│   └─user at 0.service …
│     ├─app.slice
│     │ ├─pipewire.service
│     │ │ ├─9730 /usr/bin/pipewire
│     │ │ └─9739 /usr/bin/pipewire-media-session

    * What outcome did you expect instead?

No pipewire process since it does not seem to be useful for this use case and it might increase the attack surface of the system.

I do not know if this problem is better fixed in pipewire or systemd...
