I suppose we'll continue to have alternative with the init=
commandline option. If you look at the boot process today, we do
already rely on features (CONFIG_*) for bootup. Changing the default
to have CONFIG_CGROUP=y (without any of the controllers) would work,
won't it? Is that too high an overhead/build or runtime wise?
