Title: virtual/linux-sources unmask required Author: projectmoon Posted: 2023-04-14 Revision: 1 News-Item-Format: 2.0 Changes to the linux-sources virtual have required that this overlay patches that ebuild when using the libre-kernel. If you have set up this overlay to only unmask specific packages, you should also add the linux-sources package to your package.unmask file: virtual/linux-sources::projectmoon This will prevent portage from also installing linux sources package like gentoo-sources when you already have the libre-kernel installed.
