Whonix images will be build with packages from Whonix developers repository. No packages will be build locally.
This option is optional.
This option is opt-in.
This option is useful for me during development, during creation of developers-only test images. It saves a ton of time having to rebuild all packages again and rebuilding these packages over and over again for each build.
This option might be useful for other developers who work on aspects of the build which is not related to any contents of any packages.
Builds which will be redistributed to users (those announced in Whonix News Forums) will still be build from locally build packages to ensure consistency.
--remote-derivative-packages true Kicksecure XFCE images were build in around a half hour.
