Somebody else could answer this better than me, but I'll give it a shot.
The guix-daemon is indeed laconic, even with --debug. Here, is what it
prints when I start it manually and run `guix gc -d /gnu/store/...-hello`:

---
# /root/.guix-profile/bin/guix-daemon --build-users-group=guixbuild --debug
extra chroot directories: ''
automatic deduplication set to 1
listening on `/var/guix/daemon-socket/socket'
accepted connection from pid 9343, user leo

On GuixSD, it seems that the daemon just prints to the console. I have a
non-graphical system and the daemon's output is rather annoying in the
rare case that I am sitting at the machine.

If you are looking for logs of package building, you can do `guix build
foo --log-file`. You will often need to add `--no-grafts` to see the
"real" build log instead of the log of the grafting operation.

Does that help answer your question at all?
