| # Stop conditions for this job deliberately omitted: D-Bus clients |
| # routinely terminate with crashes when dbus-daemon terminates before |
| # them. Ordering process termination with upstart is hard, so we |
| # simply leave dbus-daemon running to ensure the rest of the system |
| # can shut down cleanly. |
