If you sent individual mails to the list on different topics, it's much easier to follow those
discrete discussions.

I'm not convinced this requires a change to Upstart as it should be easy to write a shell script
that produces output in whatever format you choose combining the output of initctl and ps. There may
be timing issues there where a process ends between the initctl and the ps, but the same is true of
putting the functionality into Upstart.

Also note that we cannot change the default 'initctl list' output as it would break any number of
tools. For a more verbose explanation of initctl output that the man page, see:

    http://upstart.ubuntu.com/cookbook/#initctl-status

Note that there is a plan to produce a chkconfig-like tool for Upstart that is partly developed
currently. That would show some of the information I think you are after.

Also, have you seen this?:

    http://upstart.ubuntu.com/cookbook/#controlling-upstart-using-d-bus

Specifically,

    http://upstart.ubuntu.com/cookbook/#list-all-jobs-via-d-bus

You could write a program/script in almost any language that uses D-Bus to produce output as you desire.

Kind regards,

James
