Here are two articles from Daniel Robbins, the Pres of Gentoo, on /dev/shm. It is used as devfs.

They are part of a great series he did on advanced file systems. If you are interested in devfs, reiserfs, jfs and xfs, I'd recommend these. Go to:

and scroll down to: Common threads: Advanced filesystem implementor's guide. You'll find 13 well written, easy to understand articles on them.
