Nothing to laugh about 'devfs', it still has some crucial advantages over the abomination called 'udev', and as to that, please consider that 'udev' actually relies on something that is equivalent (but badly) to 'devfs', please check the output of 'cat /sys/block/sda/dev' for a laugh on how clever and nasty GKH is.

The device numbers are critical information for creating a device node. It isn't equivalent to devfs at all.
Where devfs got into trouble was the creation and destruction of device nodes and the permissions on the nodes.
There is hardly any advantage to devfs over udev when a daemon has to be running to update device node permissions according to system policy. If you have that daemon it may as well be responsible for creating the nodes too.

A picture of Greg with his goggles pushed up! You're right, that is clever.

That's quite a look of surprise on his face!
