Hi,

I have guix system installed and want `loginctl poweroff` to work. I'm 
logged in via ssh. The vm is started using
qemu-system-x86_64   -drive media=disk,file=geex-unenc.img,format=raw 
-bios /usr/share/ovmf/x64/OVMF.fd  -m 2G   -smp 3 -nic 
user,model=virtio-net-pci,hostfwd=tcp::2223-:22 -enable-kvm


Currently loginctl does not work:
$ strace -o loginctl.str loginctl poweroff
returns 1 and prints no errors.
loginctl.str shows some partial error message. I don't know how to get 
loginctl or dbus to be more verbose and show me the error. 
/var/log/secure does not show anything regarding that error.

$ loginctl list
SESSION UID USER SEAT  TTY
      c1 983 gdm  seat0 tty7

1 sessions listed.


First I tried configuring %base-services plus elogind-service-type, but 
it didn't work, so I tried %desktop-services, and it still doesn't work, 
but I'm sure it should. My (approximate) configuration.scm is attached.
