Thanks, I noticed the issue as well on my last guix pull! :)

However, shouldn't it be `min` still?

On big partitions, 5% will be high, so we don't want to display a
warning then, we only display it when lower than 5GiB, the minimum.

On small partitions, 5GiB is too much, so we don't want to display a
warning then, we only display it when lower than 5%, the minimum.

Thoughts?
