great, thanks a lot! I applied and pushed this patch, and dropped fdisk
from the inputs. I am happy to report that genimage now builds on all
our four architectures, instead of just x86_64.

So, do we drop fdisk, which now is a leaf package?

Also, I tried updating genimage to version 12, but there is still a test
failure even on x86_64:
   FAIL: test/basic-images.test 7 - mke2fs
Here is the diff of the test:
