Gentoo Linux maintains its own kernel builder and initramfs generation utility called "genkernel".
It looks like some attempt was made to make 10_linux compatible with initiramfs images created by genkernel. However, this support is currently broken. There are two problems. Firstly, genkernel initramfs images are named like so: initramfs-genkernel-$ARCH-$version 10_linux currently looks for this: initramfs-genkernel-$version The simplest solution here would be to use a wildcard beteen genkernel and $version. Secondly, genkernel looks for the "real_root" kernel command line option to determine the root filesystem. This is a holdover from the days when we used true initrd images and we needed to use root=/dev/ram0. I have attached a rough patch that resolves these issues. I would appreciate any feedback you can give me. My goal is to move this upstream so that I will not have to rebase it in the future.
