I don't particularly care if it's automatic, manual, or by
phase-of-moon. The point is that some process needs to add this
while clause to the MySQL-or-whatever config file in question.

And that's a problem. Provisionally I'd invent a scheme whereby a
section of the upstart files are marked along these lines

### BEGIN AUTOMATED SECTION ###
## added by PowerManager
while ac-powered
## added by NetworkManager
while has-default-route
### END AUTOMATED SECTION ###

but IMHO that's really ugly, and Debian-based distributions don't play
well with that kind of thing.

A possible alternate way would be to support clauses like

# cat /etc/event.d/PowerManagerMods
modify mysql-server
	while ac-powered

which would have the exact same semantics. That'd also be a rather easy
way to disable a service. All without touching said service's own config
files.
