Build image from binary image release including /usr filesystem

[cornelius-keller]

Hi @moul,

when I created an image using your Makefile it did not include the /usr filesystem and was not able to boot because the /sbin/init is a symlinc to /usr/lib/systemd/systemd which was missing.

I'm sure that is not perfect ( as I am very new to scaleway) and there is probably more to do but at least I was able to boot the instance and ssh into it if I add a cloud-config with my public key during the image creation with my version of scaleway-coreos here: https://github.com/cornelius-keller/scaleway-coreos .

Open issues are:

• Coreos is waiting for a disk labeled OEM to be mounted at /usr/share/oem , containing the cloud-config.yml . Putting the file there during image creation provides a cloud-config and lets me login into the instance, but coreos is waiting for the device to be mounted anyways.
• There must be a better and more generic solution for the coudconfig. Like it is now everybody has to build a custom version of this image containing the custom cloud config.
• I had a quick look into the makefiles and I'm sure there are a lot of other scaleway specific customizations to make this work really smoothly.
