Hi,
I am new to the list, so please forgive and correct me if this is
out of order.
Quoting David A. Bandel on Wed, Aug 08, 2001 at 09:33:51PM -0500 :

Although limited knowledge exists, this is the preferred method for
managing devices in the 2.4 release of Linux. It should be covered
wherever it is decided to cover mknod. I actually teach this in my
fundamentals course since it is necessary to create device files in
some cases just to get functionality from common hardware (eg. IDE,
SCSI, Audio, USB, etc.)

I agree, however, there appears to be no mention of this in level 1.
There is mention of /dev in comments to 1.104.1 but I was not able
to find any mention of /dev or mknod or MAKEDEV anywhere in
1.104 (Devices, Linux File Systems, Filesystem Hierarchy Standard)
or 1.105 (Kernel).

It is part of the procinfo package. It basically summarizes information
found in /proc/dma /proc/interrupts and /proc/ioports.
