This isn't `nice`, but the daemon does take the argument '--cores',
which you can use to limit the number of CPU cores used by the daemon.

My experience on spinning disks is that the true bottle-neck is disk
I/O, so I've used `ionice` when starting the guix-daemon with systemd.

I don't know how to make that happen on GuixSD.
