this is a bit of a hack but I wanted to see if it had any utility during development before making it all pretty. Essentially this is a copy of build_image but instead of building up an entire image it simply puts the files into directories on disk to be ran with systemd-nspawn/lxc/etc

This script is used to build a CoreOS container. CoreOS comes in many
|
|
different forms. This scripts can be used to build the following:
|
|
|
|
base - Pristine Chromium OS image. As similar to Chrome OS as possible.
|
|
dev - Developer image. Like base but with additional developer packages.
|
|
test - Like dev, but with additional test specific packages and can be easily
|
|
used for automated testing using scripts like run_remote_tests, etc.
|
|
|
|
Examples:
|
|
|
|
build_image --board=<board> dev test - builds developer and test images.
|
|
build_image --board=<board> factory_install - builds a factory install shim.
|
