• (REG) OK, pushing my own barrow here. Devfs allows device drivers to have a direct link with device special files (what you see in /dev). The current dependence on major/minor numbers to provide this link poses scalability and performance problems. Devfs also only has device nodes for devices that you have available. Read the devfs FAQ for more details. Note that devfs went into the official 2.3.46 kernel.
