How can someone use this on NixOS without Flakes #30

Open hoh opened 3 months ago

The README.md quotes "In your configuration.nix file", but does not mention how to make comin available in the configuration.nix file.

As a NixOS user, how can I use comin with and without flakes ?

You need flakes, given the entire evaluation section of the code relies on these:

Separate to comin - I do not believe there's a way to build a NixOS system configuration (from a Git repository) without flakes either.

Since comin in not yet in nixpkgs and doesn't provide a default.nix file, you need flakes to use it in your configuration.

Also, as said by @jpds, comin is only able to deploy NixOS machines from flakes and I don't plan to support something else atm.

(BTW, maybe this should be more explicit in the readme.)

Without flakes, most of the functionality is covered by the built-in: services.self-deploy.

Perhaps this could be part of the readme update?
