(and some other kernel utilities as well) A small, static set of userspace like klibc (only 5M unpacked!) with enough tools for rolling up in a standard initramfs would be especially nice, and vastly less difficult to import than qemu. It's a pain in the neck to have to build two versions of lots of bits of userspace: one stripped down and statically linked for initramfs and one full-featured for the main system. However, trying to avoid initramfs altogether is an increasingly losing battle these days, and for quite understandable reasons. klibc + md* + mini lvm2 (enough to activate volumes) perhaps? Cheers, Chris.
