The devfs in RELENG_4, which is broken, isn't the same as the devfs in
HEAD, which works quite well.  In other words: don't use devfs on
-stable: it won't work.

Are there any plans to fix this in 4.x?

Not that I know of.  I doubt phk will want to MFC it.  The devfs in
RELENG_4 is a completely different system, written by a different
author.

Comment 4 Poul-Henning Kamp 2001-05-23 21:10:11 UTC

State Changed
From-To: open->closed

Don't use DEVFS prior to late 5.0-CURRENT.
