A _bgprocess_ service is a mix between a process service and a scripted
service. A command is used to start the service, and once started, the
process ID is expected to be available in a file which Dinit can then

-the process if it runs as the system "init" (PID 1) - otherwise Dinit will
-not know when the process has terminated.

(Note, use of bgprocess services type requires care. The file from which the
PID is read is trusted; Dinit may send signals to the specified PID. It
