KernelTrap: The Case For Removing devfs

“Greg KH posted an updated patchset for removing devfs from the
mainline Linux kernel as was already done in the -mm kernel, ‘they
are the same ‘delete devfs’ patches that I submitted for 2.6.12 and
2.6.13 and 2.6.14 and 2.6.15 and 2.6.16. It rips out all of devfs
from the kernel and ends up saving a lot of space.’ The idea of
removing the unmaintained devfs whose functionality has been
replaced by udev has been discussed since late 2003, gaining
momentum in 2005 and leading to lengthy debates. In his latest
email Greg went on to explain, ‘since 2.6.13 came out, I have seen
no complaints about the fact that devfs was not able to be enabled
anymore, and in fact, a lot of different subsystems have already
been deleting devfs support for a while now, with apparently no
complaints (due to the lack of users…)'”
