How would fsck know that cgd0 is not configured?
It should try to open /dev/rcgd0a, and the open should fail.
(I would probably put a zero in the passno column in fstab to mark the
file system as not to be checked by "fsck -p".)

Yes, I think so.

I suggest another option:

    Put noauto in the options column in fstab, so "mount -a" doesn't
    mount it.  Put 0 in the passno column in fstab, so "fsck -p" doesn't
    check it.  Add your own script to do the whole cgdconfig/fsck/mount
    dance.

I don't think so.  noauto is for mount, not for fsck.

No, I think it's some other bug.
