New comment by Anachron on void-packages repository https://github.com/void-linux/void-packages/pull/27170#issuecomment-919320362 Comment: Why not make the SDK depend on the runtime? It would be bad to use conflicts when you can just depend on each other. Have both subpackages take the required files and use the SDK package to depend on those. So one can either only install the runtime or have the SDK with the runtime.
