Seem that the org.freedesktop.login1 APIs are provided by systemd.
Since we need to work on non-systemd distros too,at the very least
we'll have to keep code to fallback to using  pm-utils on those
distros.

The org.freedesktop.UPower APIs seem to be provided by the UPower
project, which was a fork of DeviceKit-Power, which in turn was
replacing HAL.

Is there any benefit to using  org.freedesktop.login1 for PM
checks, over using org.freedesktop.UPower, or vica-verca ?

Or do we need to support both dbus servics, and pm-utils.

Daniel
