Comment 4 for bug 1713490

As a follow on for ipxe we certainly want to implement a size check post build to catch changes out of a power-of-two bucket in advance next time.
Might even be worth to discuss on ipxe upstream.

Furthermore I checked that Pike (for Xenial as in sudo add-apt-repository cloud-archive:pike-proposed) does not include the ipxe from artful.
It could but it currently does not. Depending on the way to solve this we might only upgrade src:ipxe cross such rom changes in LTS->LTS.

I reached out to qemu-devel [1] for the best mechanism to catch this these days (in case there is a better one now).
