[Pkg-mpd-maintainers] Bug#1049454: mpd: purge script will forget a PulseAudio cookie in /var/lib/mpd/.config

[Alexandre Detiste]

Hi,

I know mpd does not do that _on purpose_

It it's libpulse that does that (on behalf of MPD) when called from MPD
with HOME=/var/lib/mpd/

> Deleting ".config" seems so arbitrary
It's your own private $HOME, you can.

Some other packages have similar problems...
Here HOME=/ and users get tiny useless files at the root of the filesystem:

Lightdm is even much worse,
but as long as it get cleared on purge it's fine.
