Could you please list the systemd interfaces, methods, properties, and
signals that you are planning to use so that non-systemd distros can
evaluate what to do? In Gentoo, for example, we need to decide whether
it's feasible to create a sufficient non-systemd implementation of these
interfaces on top of consolekit and acpid, or whether booting with
systemd really will become a hard requirement for us in 2013.
