In the PR 309022 i want to update the DRBD out of tree kernel driver and at the same time i want to align the code to the Nix standard build environment.
A nix-build -A pkgs.linuxPackages.drbd is successful, but returns a depmod warning. Can the missing System.map file be ignored (the related test is successful) or how should that be fixed in a Nix environment?
