Was waiting eagerly for Linux 4.17-rc2. It was late. Turns out build failed for some archs.
But also, the ones that succeeded (such as amd64) are unsigned. They are also anaemic at about 7MB compared to over 50MB for normal generic images from the mainline.
Why are they unsigned, and why are they so small, just because builds for other architectures failed?
Thank you for any information!
