Hello Guix! Following a discussion we had at the GHM today, here’s the tip of the day!
People often ask how they could store their GuixSD config alongside the instantiated system in the store. Guix maintainers usually grumpily reply “nah, don’t do this, because the config file is not self-contained, so that’s not good enough.” But wait: we can already store the config file in the instantiated system! Here’s how: (operating-system ;; … (services (cons (simple-service 'store-my-config etc-service-type `(("config.scm" ,(local-file (assoc-ref (current-source-location) 'filename))))) …))) You instantiate that, and then /etc/config.scm (aka. /run/current-system/etc/config.scm, aka. /var/guix/profiles/system/etc/config.scm) contains the config file. Pretty neat no? Enjoy! Ludo’.
