On my system that directory is empty.

    zhaoway> this file, hmm. Now after I clean up the dir.conf:

[521] [snoopy:bam] ~ >grep INCLUDE /etc/devfs/*.conf
/etc/devfs/devfsd.conf:INCLUDE				/etc/devfs/perms
/etc/devfs/devfsd.conf:INCLUDE				/etc/devfs/dir.conf

only devfsd.conf should include anything. Perhaps your dir.conf file
was somehow corrupted?

dir.conf is normal.

I will attach my conf files for you (they are small, so it should be
OK). All of this live in /etc/devfs.  No other files exist. Some empty
directories exist:

8	/etc/devfs/symlinks.d
8	/etc/devfs/devices.d
4	/etc/devfs/conf.d
52	/etc/devfs
