My original intent was very simple: you can turn off all upstart jobs
one-by-one. You cannot remove some packages (that you may not need),
like wirelesstools. I needed it for some of my configurable ISO images.
So I added an option to turn them off, too. As a side effect, you get
less unneeded commands in PATH. I do not think that  usage of cleanStart
in cron job is consistent with help text, but help text was written
before the cron job (and cron job was not written by me).

That would mask original functionality..
