Subject: devfs not ready for prime time yet?
Sender: owner-cvs-all@FreeBSD.ORG
Precedence: bulk

    I tried messing around with devfs, using a minimal /dev (just std
    devices like /dev/zero) and then immediately mount_devfs'ing over
    it at the top of /etc/rc.

    It almost works.  For some odd reason, wd0 gets really, really confused.
    When I try to boot using devfs for /dev, fsck fails instantly trying
    to fsck IDE drives on wd0.  If I drop into /bin/sh, the first time I 
    run disklabel on wd0 the disklabel only sees wd0c. The second time it 
    sees wd0a,b,c,d,...g.  The third time it gets an ioctl error.  The
    fourth time it seens all the partitions.

    It then alternates between getting an ioctl error and seeing all the
    partitions.  At some point down the line, disklabel simply locks up
    in an unkillable fashion.

    devfs looks like it should work, but there are obviously some serious
    problems left with it.  Is anybody working on devfs ?  I would, ultimately,
    like to see the kernel auto-mount /dev as part of the boot sequence, just
    after it mounts the root drive, but for now I'd be happy if I could mount
    it over a minimal disk-based /dev in /etc/rc.
