Systems where both /usr and / +are on the same filesystem may use an initramfs if they wish, or choose not +to. + +Historically, Gentoo has tried to make the separate filesystems use case work +anyway. Despite all our efforts, it is broken and continues to get more broken +under various configurations. The only workable solution is to support +separate /usr but only when an initramfs is present.
