build-variant-from-local-kits

To build a Bottlerocket variant from local kits, run brdev twoliter use-local-deps, set vendor = "local" in Twoliter.toml, update with twoliter, and then execute cargo make with the desired BUILDSYS_VARIANT and architecture.

Before building a Bottlerocket variant locally, you need a running local registry, a Bottlerocket variant repository, and a Twoliter setup with vendor overrides configured to use local kits.

Using local kits reduces reliance on upstream sources and enables end-to-end validation by producing bootable images for local testing before you publish kit changes upstream.

Yes, you can specify the target architecture by running cargo make with the BUILDSYS_ARCH environment variable, such as setting it to aarch64 to build the variant for that architecture.

Yes, building locally requires both brdev and Twoliter. You use brdev to apply local dependencies and Twoliter to update your configuration before running cargo make to build the variant.

After building the Bottlerocket variant locally with cargo make, the resulting bootable image file is located in the build/images directory and can be viewed using the ls -lh command.
