Understood.

(I wonder if the QEMU Guest Agent can serve a similar purpose.)

I think this is unfair criticism: Xfce is actively maintained, with a
large user base.

Right.  I wouldn’t mind GNOME, but one reason we went for Xfce is that
GNOME is just too big, at least as currently packaged in Guix.

Oh, I wasn’t aware of that, that should certainly be fixed.  (I fixed a
similar issue in GNOME some years ago, and I’m confident it’ll be easier
to fix in Xfce because it doesn’t have all those layers and daemons and
JavaScript and DBus interfaces.  :-))

That’s a general issue with all Xfce installations, not just in the VM
image, right?

Thanks,
Ludo’.
