[laptop-mode] Making install.sh more distribution independent

Sure, I can do that. For Debian I kind of copied everything, but it
would be nice if other distros could simply call install.sh.

Sounds like a good idea. I can do that.

OK, sounds very acceptable too.

Hmmm, can you explain the use of this for package managers? I'd expect
that you would want to be able to enable *everything*:

FORCE_ALL_POWERMGMT_TYPES=1 ./install.sh

so that you as a package writer have all files at your disposal below
$DESTDIR, installed in the correct locations. And then you yourself can
install only the subtrees intended for the power management daemon that
you want. Or not?

Cheers,
Bart
