    I wonder if we should support multiple bootconfigs instead of updating
    the size/checksum/magic?

    So the end of the initrd would have:

    [data][size/checksum/magic][more-data][size/checksum/magic]


    And the kernel could do the following:

    1. read the end of the initrd for bootconfig
    2. If found parse the bootconfig data.
    3. look at the content before the bootconfig
    4. if another bootconfig exists, goto 2.
