The concrete problem is this:

1. nginx is running with config file A
2. make some change to nginx config
3. run guix system reconfigure (which builds a new nginx config file B)
4. run herd restart nginx
5. nginx is still running with config file A

After reverting this commit, if I perform these steps, I end up with
nginx running with config file B in 5.

I still get a bootloader line.
