When boot media has been found, udev will be killed. If udev is busy
to mount other medias at the killing time (especially medias is many),
the above issue will occur occasionally.
Invoke `udevadm settle' before killing udev will resolve this
issue, it watches the udev event queue, and exits if all current
events are handled.
Use variable `_UDEV_DAEMON' to replace hardcoded `udevd' to keep
consistent with previous.
