I agree that 'guix gc' deletes too much, but it's probably not dangerous. You will just see some downloads and builds repeated when reconfiguring later. I believe 'guix gc' deletes items that are not garbage to me (but I am new to Guix). Based on friendly advice I received, I currently use these settings: (guix-service-type config => (guix-configuration (inherit config) (extra-options (list "--gc-keep-derivations=yes" "--gc-keep-outputs=yes")) ...
