  It's $MDEV, according to the documentation.  It also says...

  As I read it, "exit 0" won't create the necessary nodes, and parsing
stops, because a match has been found.

  I hadn't thought of that.  /etc is more likely to be present at
bootup.  I had originally intended this for stuff done by the user well
after booting.  But some people may ant it available earlier.  So
/etc/mdev.d seems to be the most logical choice.
