The attached cpio-parsing code compiles to 458 bytes on x86-64 and 476 bytes on i386, and that is without any library dependencies at all. Again, it will completely stop at the first compressed data item, so any such kernel objects absolutely will have to be first. In good Linux tradition, it is also completely untested. However, given that very reasonable size I would think that this is a reasonable approach. Anyone who has a better suggestion for the namespace than "kernel/"? -hpa -- H.
