Thanks, I've figured that one in the meantime myself.
Still, it would be nice if there was a way to see which rules were hit,
when and why.

And if possible, similar tool for .link files. 
As it is now, I had to enter custom udev rules to rename my nics.
Name="xyz" settings in link file wouldn't do it for me and I don't
remember being able to get any clue on the reason from systemd-udevd.

I'm sure there are plenty of cases where this could come very handy.
