    In general I agree. The cost of a second kernel and initrd can be
    prohibitive in the smallest systems, and if you do a crash capture
    with using a standalone app that is reinventing the wheel.

    That said. I can happily run kdump with only 16M-20M reserved.
    So on many systems the cost is affordable.
