I'd rather see libvirt dependent on pm-utils than dbus. Moreover, the
methods paths are not unified AFAIK. For instance, I'm using KDE and on
my system it's:
org.freedesktop.UPower.HibernateAllowed()
org.freedesktop.UPower.SuspendAllowed()
Paths you've provided don't exist at all on my system.
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
