Use a nixos-unstable revision the channel has not yet advanced to (but the tested jobset has succeeded already), so we'll benefit from the polkit security update. * //users/grfn/home/games: replace multimc with polymc. Seems like this is the conclusion in in the trademark saga. * //third_party/terrform-provider-glesys: use new mkProvider interface See https://github.com/nixos/nixpkgs/commit/e7dbfd7ece0e Change-Id: Ieb76a3d73c42ce1fa34050ac797fa4e3a905e8ef Reviewed-on: https://cl.tvl.fyi/c/depot/+/5075 Tested-by: BuildkiteCI Reviewed-by: tazjin <tazjin@tvl.su> Reviewed-by: grfn <grfn@gws.fyi>
