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.
