dynamically created /dev/null is a regular file

[Brook Milligan <brook%nmsu.edu@localhost>]

I have been installing some -current systems (cvs from 201505311600Z to be exact) that dynamically construct /dev when booting.  This seems to be the default behavior of rc when /dev is effectively empty.  The problem is that /dev/null routinely ends up being a regular file not a device file.  How and when are the device files created and why is null created wrongly?  Could it have been created somehow before the rest of the devices are created dynamically?

Is this related to kern/33023?

Thanks for your help.

Cheers,
Brook
