Hmm, I can mostly agree with that. The only real use I can think of for devfs.conf is when the devfs binary is corrupt. > The devfs(8) documentation is lacking in a > complete, working example, What's wrong with the EXAMPLES section in devfs(8)? > any documentation of the rc.conf variables > (which also aren't documented in rc.conf(5) either), and any mention of > that the purpose or usage of lines like: > > [devfsrules_unhide_basic=2] See devfs.rules(5), third para of DESCRIPTION. I agree it could use an example, and some explanation that you have to enable the ruleset in /etc/rc.conf.

Most of the things I learned while configuring FreeBSD are documented here. http://www.xs4all.nl/~rsmith/freebsd > Comparativly few people will want to do anything more than make a device > or two more accessable. Agreed. But the mechanism is more general because devfs can be used in multiple places (e.g. jails).
