Launching pipewire and wireplumber is racy, as there is an arbitrary amount of time between pipewire is launched, and that the socket is bound. In order to eliminate this race, bind the pipewire sockets ourselves, and launch pipewire (and wireplumber) when there is activity on the socket. This is using the systemd method of doing socket activation, which consists of passing the number of passed file descriptors via $LISTEN_FDS, and the pid of the launchee via $LISTEN_PID. The former is easy, just pass the file descriptors, but the former is more tricky when using python, as executing code before exec() is poorly supported and likely to be deprecated. To address this, socket activation services are wrapped in a socket-launch.sh helper which sets the $LISTEN_PID to itself before calling exec().

Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork of Clutter, a scene graph and user interface toolkit.
Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
