"If you want an even more succinct summary of the plan, it's 'move all
to |/usr|'. Or, more specifically, "instead of spreading RPM package
content all over the place in the filesystem, and artificially separate
|/bin| from |/usr/bin| and |/lib| from |/usr/lib|, move all content to
|/usr| and provide only symlinks in the root filesystem."
