:I guess this won't work prior to mounting /dev, right?  This would break having root on vinum and loading vinum from loader :/
:thanks for your work

    The direct dev accesses vinum does are just plain and simply illegal.
    They can't be used.  They are broken in so many ways it isn't even
    funny.  Not just the open/close issues, but also the max DMA size
    issues which vinum ignores completely.  vinum is totally incompatible
    with NATA at the device level.  We *have* to go through a vnode.

    This leaves us with synthesizing a vnode from the device list based
    on the device name templates, which is about 8 hours of programming.
