Subject: gnu: emacs-nix-mode: Fix build by switching upstream source.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

'nix' version 2 doesn't provide Emacs libraries anymore.

* gnu/packages/package-management.scm (emacs-nix-mode): Do not inherit
'nix'.  Switch upstream source to <https://github.com/nixos/nix-mode>.
