udev or devfs or neither

I was unaware of the fact that a computer can plod along without EITHER devfs or udev. I thought they had to have either of the two.

So how does one know there's uses ?

I found this:

"How do you know if you have devfs or udev? devfs /dev/.devfsd exists udev < 1000 files in /dev neither > 1000 files in /dev (created at installation by MAKEDEV)"

So if you dont have /dev/.devfsd then do this.

 ls /dev/ | wc -w

My personal computer, which I know runs udev returned 699, while my Sarge boxes both returned a number over 1,000

You learn something new everyday
