* suntrold is a oneshot service and spawns a subprocess which is required
  for the rear camera. Since [1] oneshot services' process groups are
  killed which prevents suntrold from working correctly.

* To work this issue around create a non-oneshot service, suntrold.sh, which
  never exits, so that suntrold can be started from it and it's subprocesses
  will not be killed.
