>Subject: [PATCH] [PATCH v3] Implement systemd socket activation
>
>Use libsystemd-daemon and two unit files to provide socket activation
>for the default native unix socket ($XDG_RUNTIME_DIR/pulse/native)
>from the user manager.
>In the future this would allow to drop all the complex server
>location and autospawn code, and just rely on the user manager
>to do the right thing.

>v1: from Giovanni Campagna <gcampagna@src.gnome.org>
>    http://lists.freedesktop.org/archives/pulseaudio-discuss/2013-December/019662.html
>
>v2: from Javier Martinez Canillas <javier.martinez@collabora.co.uk>
>    Changes since v1 addresses all the concerns raised in:
>    http://permalink.gmane.org/gmane.comp.audio.pulseaudio.general/19365
>  - Add SYSTEMD_DAEMON has a new configure option
>  - Check for HAVE_SYSTEMD_DAEMON instead of HAVE_SYSTEMD
>  - Wrap unused variables under #if defined(HAVE_SYSTEMD_DAEMON) to
>    avoid compiler warnings when libsystemd-daemon is not available
>  - Fix coding style issues
>  - Add configure output for HAVE_SYSTEMD_DAEMON
>  - Improve debug log message
>  - Add missing pulseaudio.{service,socket} files
>
>v3: from Alban Crequy <alban.crequy@collabora.co.uk>
>  - rebased on git master
>  - fix module_native_protocol_fd_la_CFLAGS
>  - pulseaudio.service with WantedBy left empty?
