# Stop conditions for this job deliberately omitted:  clients
# may terminate with crashes when mojo_shell terminates before
# them.  Ordering process termination with upstart is hard, so we
# simply leave mojo_shell running to ensure the rest of the system
# can shut down cleanly.
# mojo_shell is, for systems using mojo IPC, analogous to dbus-daemon, so the
# two jobs have the same start up requirements.
