Yes.  Also, on FreeBSD, there's only one reader of /dev/devctl, which
is devd(1), which is likely the only program to ever read from it.  It
then writes all the messages it gets over the /var/run/devd.pipe.  The
reason that I added the pipe is so that devd can also broadcast
network events and the like in the same format as other events.

Also, the reason I chose text over binary was that I didn't want devd
to know jack about how any specific bus was implemented...
