I made an Emacs distribution with the help of nix. You can even replace the default Emacs config with your own elisp files, provided you make extensive use of “use-package”
It imports all your needed dependencies by reading what packages you depend on in your elisp config, then making a list of dependencies and load that into nix via an import-via-derivation.
The readme.org probably needs so expanding on how to use the standard distribution, but I thought I’d share what I had made so far on the forum
