That documentation is the classic legacy way. It has since been

Actually, this information is outdated too.
Nowadays, the devices in /dev are created by the kernel itself using a

permissions.

I stand corrected. And I am only four years out of date! :-)
Thanks for the nice reference too.

I'm not sure about that. That article doesn't say anything about it
being the "standard way" and from what I have seen udev is still pretty
much part of any core Linux system and used extensively as described.
Back when I used Gentoo most times the devtmpfs system wasn't even
enabled in my kernel or in its default configs. From all I can find out
devtmpfs is merely an option most distributions don't actually use that
much because udev already handles these things.
With udev being merged into systemd and their devs working on dropping
support for non-systemd machines this may change, however, and devtmpfs
may be used as one half of a new device management system for
non-systemd machines.
