There are a lot of stupid expedient things that people making embedded
products like to do.   Tell them to write a 5 line /sbin/hotplug script.

udev isn't too expensive to run on the embedded platforms, and if they

a possibility.

Nope.   I don't want any piece of ownership of devtmpfs.  I have sent
the only patch I am comfortable with.
