thanks, I've started looking through it. For now dumping into
/run/udev/rules.d is a lot easier to add than hooking up umockdev - we have
our own test framework around check, umockdev would be a bit more extensive
to change bits and pieces around.

That's mainly because we don't use the evemu format, we have a bunch struct
input_event arrays or wrappers around it. We don't use the recordings, it'd
be a bit unwieldly for the various interactions that we're testing.
So to switch to umockdev we'd have to juggle a lot more things than we do
now, that'll take time to write.

Cheers,
