I tought that this should be handled by invoke-rc.d itself. The manpage
states that:

	invoke-rc.d introduces the concept of a policy layer which is
	used to verify if an init script should be run or not, or if
	something else should be done instead. This layer has various
	uses, the most immediate ones being avoiding that package
	upgrades start daemons out-of-runlevel, and that a package
	starts or stops daemons while inside a chroot jail.


So my assumption was that invoke-rc.d detects if it's invoked inside a
chroot, and doesn't start the service in that case.
