It's been hashed and rehashed back when udevd were invented to replace devfs and we returned back to traditional kernel-generated names for a base. Oh well... That's, actually, _excellent_ news, something that bothered me for all these years since 2.4 kernel - that I don't have some devices in /dev (because they're named differently or moved to a subdir) which are mentioned in dmesg or sysfs. Hooray! Will check for all sound (/dev/snd/), input (/dev/input/), usb (/dev/usb/) and oh, the famous tun (/dev/net/tun) devices - you intrigued me!.. ;) Thanks! /mjt
