Use systemd for suspend and hibernate
When running under systemd, call into systemd for suspend and hibernate instead of pm-utils. To capture resume events, install a small script that gets executed by systemd after resume and sends a dbus signal back to upower. To make this work, the upower backends gain a new signal, ::resuming, that they can optionally emit to signal that a resume happened. Backends opt in to this by returning TRUE from up_backend_emits_resuming(). In this case, upower doesn't assume the sleep command to block until resume, but instead waits for the ::resuming signal from the backend. The only backend that uses this mechanism is the linux backend when built with systemd support. Signed-off-by: Richard Hughes <>
