I've still some bug report of people using home-compiled devfs kernels on Debian. So people still use it. You say "devfs" is buggy, but it works on nearly all cases, so people tend not to switch. The worse is the lack of stable name of devices, in udev too. I.e. microcode loader (Intel CPU) needs a device, which was so named (last time I controlled): # device name in LANANA / devices.txt DEVICE=/dev/cpu/microcode # device name in devfsd DEVICE2=/dev/misc/microcode # device name in udev DEVICE3=/dev/microcode If we a coherent *default* device name scheme, the switching from a kernel utility to other would be trivial. ciao cate Note: /dev/cpu/microcode was also created by devfs until recent 2.4 kernels and the whole 2.6 serie. > > >>That being said, mid-2005 would be an appropriate time to remove devfs.
