Just for the record, the statement I got from Kay Sievers from udev about this is that
we shouldn't use the "last_rule" at all because it could create an "inconsistent behavior"
and it should be removed.

The truth is that with "last_rule" some of the problems could stay hidden forever, because
only when something really breaks, people will react promptly :) So if we're going to play
udev rules, others should play device-mapper rules as well and do not try to process dm
devices when they are instructed to do so by means of checking certain environment variables
we set for them.

(Basically, there are two options - either we check the state and use last_rule and other
rules won't be processed or we rely on others checking these flags/env vars.)

Any comments are welcome..
