After my second installation of Guix SD i changed a lot stuff in the config file and reconfigured but somehow that didn't work properly. So i ended up having to do single edits to the config and then running reconfigure after every edit. That worked nicely.
Also I couldn't help but think that in GUIX we would need to have multiple declarations on the config for multiple virtual-hosts in nginx and other web servers. Right ? This means we should run a guix system reconfigure even if we want to add another virtual-host. I'm not wary of "guix system reconfigure", it just feels "new". I guess I will have to ease into it. :-) > >> 3.
