Using parallel_emerge has been disabled by default for all commands except build_image for quite a while now, build_image kept it just because it was still a bit faster than normal emerge. Keeping parallel_emerge complicates future changes to build_image so it needs to drop it entirely. Since that means nothing uses it by default we might as well just rip out support for it entirely.

This script is used to build a CoreOS image. CoreOS comes in many
|
|
different forms. This scripts can be used to build the following:
|
|
|
|
prod - Production image for CoreOS. This image is for booting.
|
|
dev - Developer image. Like base but with additional developer packages.
|
|
container - Developer image with single filesystem, bootable by nspawn.
|
|
|
|
Examples:
|
|
|
|
build_image --board=<board> dev prod - builds developer and production images.
