Comment 6 for bug 94873

Although custom actions would allow a great deal of flexibility, this might be somewhat of a "double-edged sword".

After discussions at UDS-P (https://blueprints.launchpad.net/ubuntu/+spec/foundations-p-upstart-for-admins), it was generally agreed that a first step would be to enhance the abilities of the 'reload' and 'restart' commands. Since the current command set covers 99% of all known use-cases so custom actions are being deferred for the time being.
