See https://github.com/NixOS/nixpkgs/issues/437208#issuecomment-3288623669 Depends on https://github.com/NixOS/org/pull/172 As documented below, the idea is to essentially group all changes rebuilding all VM tests with kernel updates and merge them together into `master` whenever the Linux kernels get updated. This documents the workflow of updates in the nixpkgs manual. While at it, I removed the README from the packages because * it's horribly outdated * I didn't even know it exists which confirms that its discoverability was very poor and added the relevant portions into the nixpkgs manual as well.
