Runlevel and version are state, not actions, so they belong behind org.freedesktop.DBus.Properties rather than another method each. Finit also claims org.finit on the system bus when it finds one, so ordinary D-Bus clients can reach it without knowing about /run/finit/bus. Opportunistic on purpose: no dbus-daemon is a normal state for the systems Finit runs on, not an error to report. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
