I continue to ponder if we ought to have init level 4 in Fedora, meaning 
"running on battery". Although I start and stop a bunch of services 
going between 4 and 5, in reality most of them have no connection to the 
battery status. For instance, I run ntpd and cups at level 5 but not 4, 
because when I'm on battery, I'm away from home and naturally I do not 
want either of them. This is, of course, bogus. However, there's one 
service which may make the whole idea worthwhile: *crond*.

This sucker runs a whole bunch of things which definitely depend on AC 
power and not on network status: makewhatis, prelink, logrotate, and so 
on. Switching it on and off makes perfect sense. If only I were able to 
figure how to make a hysteresis. If I plug and unplug power quickly, 
apmd fires, init flips on and off, gazillion freaking scripts run. Or, 
more realistically, I unplug and replug when migrating between outlets. 
So, there must be some sort of a delay.
