I think this is something to aim for as a goal. 

No, it may not be a /dev you'd want to use normally, but from a robustness 
and stability angle, having a policy that says "we should aim to _work_ 
even without udev running at all, even if you don't get the frills". So at 
that point devtmpfs actually offers users something.
