Subject: detecting devfs from userland?
Sender: owner-freebsd-hackers@freebsd.org
X-Loop: FreeBSD.org
Precedence: bulk


Is there anyway to detect if the running kernel was built with
-DDEVFS, other than trying to mount -t devfs ? (i.e a way that
doesn't require root privs? sysctl -a is of no use here.

Cheers,
Julian.
