I tend to disagree here. The headers are not "from" the kernel, since
in practice, we download the kernel source code twice and extract it
twice. So the "as kernel" really seem better. It could be "like kernel"
as well, but "from kernel" seems wrong.

However, I'm all for improving the help texts to make this clearer.
