    No it's not.

    The practical goal is that a distribution can enable essentially every feature
    in the kernel and not be forced to use one.

    The most similar example I can think of is the dhcp client in the kernel.
    Even when compiled in only if you enable it on the command line (aka ip=dhcp)
    does it enable and attempt to network boot.

    Mouting on /dev might be sane if it was enabled by a kernel command line option.
    By default it is wrong.

    Dynamic minors is right on that hairy edge. I'm puzzled know why we
    can't have the first N devices use the static assignment and the rest
    of the devices use the dynamic minors.
