Hi Clément and Ricardo, Thanks for your replies!
I conclude from them that there is no clear recommendation yet for dealing with this situation, so for the meantime I applied >> 1) update /etc/systemd/system/guix-daemon.service >> to point to the current daemon? If so, is >> /root/.config/guix/current/bin/guix-daemon >> the right (stable) path to use? I prefer to point to /root rather then to my $HOME which is less reliable for reasons completely unrelated to Guix (it's on a zfs volume shared with macOS). So far (i.e. for about a day) this seems to work fine! Thanks again, Konrad.]
