If you have made git commits out of your changes, you can do `guix pull --url=/your/guix/checkout`. Otherwise you can use the './pre-inst-env' script, as described in the link above. "./pre-inst-env guix system reconfigure my-config.scm" will create a new system generation using only code from the git repository.
