Maybe someone can strace udev or look at the source and see what the
difference between those two settings is?

If people want to use udev at the same time as lvm2/device-mapper they have
to configure it to ignore device-mapper devices completely.  Its
asynchronous design just doesn't fit alongside code that is creating,
using and destroying short-lived devices.
