salt.modules.upstart¶

Module for the management of upstart systems. The Upstart system only supports service starting, stopping and restarting.

Currently (as of Ubuntu 12.04) there is no tool available to disable Upstart services (like update-rc.d). This[1] is the recommended way to disable an Upstart service. So we assume that all Upstart services that have not been disabled in this manner are enabled.

But this is broken because we do not check to see that the dependent services are enabled. Otherwise we would have to do something like parse the output of "initctl show-config" to determine if all service dependencies are enabled to start on boot. For example, see the "start on" condition for the lightdm service below[2]. And this would be too hard. So we wait until the upstart developers have solved this problem. :) This is to say that an Upstart service that is enabled may not really be enabled.

Also, when an Upstart service is enabled, should the dependent services be enabled too? Probably not. But there should be a notice about this, at least.

DO NOT use this module on Red Hat systems, as Red Hat systems should use the rh_service module, since red hat systems support chkconfig

salt.modules.upstart.disable(name, **kwargs)¶
