Hm, that was indeed my approach for injecting a memory size check for
livenetroot for the agama initrd that is build with kiwi.
But, I don't remember that I submitted that anywhere.

However, it's missing error handling for the case that curl cannot retrieve the
Content-Length setting.
I will work on it.
