It's can be used when starting weston as a systemd unit. 

 - notify systemd about startup via sd_notify (READY=1)
 - notify systemd that it's still alive via WATCHDOG=1
 - notify systemd about shutdow using STOPPING=1

An example unit file is being prepared upsteam:

Since we already link against libsystemd no new dependencies are
introduced and the module needs to be loaded explicitly so no risk for
running installations.
