A cleaner way to do this is to run `sudo systemctl edit guix-daemon.service`.
It will open your editor to create a drop-in override file, in this case
/etc/systemd/system/guix-daemon.service.d/override.conf, with a commented-out
version of the base unit file included. You'll want to write something like this:

```
[Service]
ExecStart= 
ExecStart=/usr/bin/guix-daemon \
    --build-users-group=_guixbuild \
    --discover=yes \
    --substitute-urls='https://bordeaux-us-east-mirror.cbaines.net https://bordeaux.guix.gnu.org https://ci.guix.gnu.org'
```

The most confusing part is that you need two ExecStart lines, one unsetting the
old value and one setting your new value.
