Package: arch-test Version: 0.20-1 Severity: wishlist Control: affects -1 + debvm
Hi Adam, arch-test already is great, but maybe it can do even more. I would like to know which architecture corresponds to a given vmlinuz image. A vmlinuz image tends to consist of a boot stub followed by a compressed ELF image. The compression scheme varies and we don't exactly know where the compressed image starts. A relatively hacky way to do this is runnig linux.git/scripts/extract-vmlinux and then feeding the output to elf-arch. Maybe we can pull part of this functionality into arch-test? The context of this is usage of arch-test in debvm. Given a root filesystem, I already use elf-arch on the contained /bin/true to guess its architecture. However the kernel image may correspond to a bigger architecture (i386 -> amd64, armel -> armhf, armhf -> arm64, etc.) and I would like to determine such cases automatically. As such, this functionality is only really relevant for architectures with sibling 32bit / 64bit architectures. There is not much ugrency to this. It just feels like arch-test would be the right place to own this functionality. Thanks for considering. If you end up considering this out-of-scope (e.g. due to the need for various decompressors), don't hesitate to close this as wontfix. Helmut
