Oops, sorry, I had a brain hiccup -- rather, forcibly mount root
(and any other fs's) as read-only:

    # mount -f -o ro /
    # mount
    /dev/wd0a on / type ffs (read-only, local)
    kernfs on /kern type kernfs (local)
    procfs on /proc type procfs (local)
    procfs on /usr/pkg/emul/linux/proc type procfs (local)

Brian.
