Re: Why do we need /dev

It was always possible to assign major device numbers dynamically.
I think what Jinesh wants to point out that , the parameer _dev itself
should not be used by driver developers.
It is something that should be obvious for the developer and treated
as a black-box , so to speak.

So is POSIX compiancy the ONLY reason the major and minor numebrs are present  ?

AFAIR you need not to worry now about it now.Kernel allocates major
numbers (not used )one for you dynamically, isnt it? This is what ldd3
says if  am right.
