I am getting the feeling that the best thing to do would be to combine
the two agents. It sounds like the main thing added by LVM-activate is
the two new modes, which could be added to the existing agent?
Especially now that the activation modes are more or less plugins to the
old agent.

LVM vs. LVM2 is confusing enough on its own, if there's an actual lvm2
project that just makes it even worse... IPaddr and IPaddr2 is a
situation we don't want to repeat. :/

Even if it means some extra work, I suspect it will be worth it in the
end to combine them.
