Checks are repeated several times

[munnik]

Is this normal behavior? Checks are repeated several times. It looks like it is doing it for every target, but I'm not 100% sure about that. It takes quite some time to do a deployment.

Adding more machines to the list makes deploy-rs really slow. With 6 machines it takes more than 15 minutes to do the deployment, most of the time is spent in checking NixOS configuration....

A recommendation would be, if you use deploy-rs with multiple machines, run one check beforehand (nix flake check -L) manually and then skip checks in deploy with -s. It becomes too slow otherwise when dealing with a few complex systems.
