Here is the shell.nix I am using for scuttlebot and git-ssb so far. It's basically the one from t:n with all the electron stuff removed.

Next step: exposing/installing the binary helpers (sbot, git-remote-ssb) so I can include them in other shells.

I also have updated the .nix files on my dotcryptix repo. Moving away from one big systemPackages towards more little shells.
