As Chris noted in a previous message the udevadm_t domain could be used from other places. This patch allows for that possibility in the near future but for the moment just makes a system bootable in enforcing mode right now. Also I didn't remove the context entries for udevadm even though on systems with a recent systemd they won't exist. At this time leaving them there may provide the best compatability options. Finally I added a udev_runtime_t watch because the need for that appeared when I was working on this. Sent again for a better sign-off.
