I'm not sure ELF should really be considered "yet another archive
system." This is analogous with keeping debug in another ELF section
for user apps. You can keep it, you can strip it, etc. Other formats
would work, but as you say you'd have to modify the bootloaders to
accept them.

These sections don't have to be thrown away after boot either. While
the sections should be marked as no-load, it may be useful to actually
load them and have the kernel explicitly toss them if it finds no use
for them. Real uses would including exporting to /proc/config.gz (if
you like that kind of thing), or providing the to kdb if kdb
is enabled.

Note that we also supply the initial ramdisk (which is loaded of course)
this way. In theory you could remove the ramdisk and replace it by
using objcopy, but we still have some things to fix before that will
work. This *is* useful for people who netboot (at least for ppc64
