One more thing: If you decide to revert the nss update (commit 4f3dcdd99b), please also revert commit 87f1c7efc1 (gnu: nss: Use 'modify-phases' syntax), to save Hydra from needlessly rebuilding several hundred packages. These two commits should be reverted together, and then re-applied together when the problem is ultimately resolved. Thanks, Mark
