devfs ve Unix
Açıklaması şöyle.

Eski Unix'te /dev dizini
Açıklaması şöyle

In 1986 (and for a few years after that still), /dev wasn’t handled by a special file system. It was generally a directory on the root file system, and its contents were largely static: a series of device nodes, created by mknod. Many systems had some way of creating the “standard” nodes, for example a Makefile in V7 or MAKEDEV.
