Is there any point in establishing an init runlevel for "undocked" operation - that is, using a laptop away from AC power? Some laptops are capable of sensing when they go on and off of AC and could change the run level on their own. I can think of situations where you would want cron to run when AC was available.
This sounds like a neat concept. Run-levels are rather limitted, but this seems to fit in with existing uses of the concept. I don't suppose there's any sort of run-level registry anywhere? -- Raul
