For multi-file uploads we should explicitly declare what the name of the .DIGESTS file should be instead of using the first file name. Relying on the ordering was subtle and easy to break.

This script is used to build a CoreOS image. CoreOS comes in many
|
|
different forms. This scripts can be used to build the following:
|
|
|
|
base - Pristine CoreOS image for generating update payloads or a dev/prod image.
|
|
prod - Production image for CoreOS. This image is for booting.
|
|
dev - Developer image. Like base but with additional developer packages.
|
|
|
|
Examples:
|
|
|
|
build_image --board=<board> dev prod - builds developer and production images.
|
|
...
