Then it's coming from some other rule. It's usually not the case.
But what I meant regarding the problem, is that it should _not_ matter if udev
does these artificial events (with 'watch') or libstorage is doing it (writing
to uevent). Both types of event sources will cause exactly the same behavior as
they both don't originate from libdevmapper, and removing them from libstorage
will only make the links not updated in case udev does not trigger the watch
events.
Some large systems, or systems using many tiny writes with 'dd', or something
similar are known to have problems with udev's 'watch' and are instructed to
globally switch this off with a custom rule containing 'nowatch'.
In short, I would not expect, that changing libstorage will solve any of the
problems we are seeing.
