As explained in more detail at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=534976 consolek-kit-daemon should provide support for saving and restoring state when it is restarted, which can become necessary e.g. if there is a security related update of consolekit.
I don't think we want to support restarting the CK daemon. Probably best to reboot if we have a problem like this.
Going to close this.
