Greg KH have released “nano” devfs patch for the current linux kernel to mitigate the concerns of embedded system developers.
However according to Greg the inventor of udev (userspace /dev filesystem), he is not going to submit ndevfs patch to the main kernel tree. He explains it in his words :
“I’m not going to be submitting this. But what it is, is a nice proof-of-concept for people who ‘just can’t live without a in-kernel devfs’ to show that it can be done in less than 300 lines of code, and only 6 hooks (2 functions in 3 different places) in the main kernel tree. That is managable outside of the main kernel for years, with almost little to no effort.”
