[1/1] add daemon mode support to pulseaudio

pulseaudio documentation recommands not using the daemon mode unless you
are on a headless system, but since that is the common case for a
buildroot installation, install the related user and groups

Dear Jérémy Rosen,

The title of the patch should be:

	pulseaudio: add daemon mode support

i.e, always put the name of the affected package first.

	bool "start as a daemon"

should be sufficient, since the option will be indented under
pulseaudio.

Missing final dot. It would be good to explain how pulseaudio is
started when this option is not selected.

Thanks!

You use a mix of spaces and tabs for indentation in this script.

That seems wrong. It should be:

As we now have support for post-build scripts, we no longer need the
hack about checking if the script is already present in the skeleton, so
that can be removed.

Committed with these fixes (and the typos Thomas pointed out), thanks.

Are you actively using pulseaudio? 3.0 got released some months ago,
care to test and send a patch to upgrade to it?

yes, I have a project using pulseaudio to build a headless remote audio system. i'll give it a try and report my findings
