No, it should not. You should only turn on something that you really
need. If you don't need an mdev.conf then you should turn support for
the config-parsing off. If, OTOH, you _know_ that you need a specific
mdev.conf, then you're supposed to use your .conf that you wrote and
that does what it is supposed to do.
mdev works fine without conf support.
