Not at all, this was the first install on that machine. The OS was even installed recently, so there can't be any remnant of the 0.15 era :). Installation went smoothly and /root/.config/guix/current was already a symlink to /var/guix/profiles/per-user/root. We ran guix pull as user just before and it worked perfectly well (with the message about migrating, although ~/.config/guix/current didn't exist). Could there be some veird interaction between sudo and these %profile-directory and %user-profile-directory variables?
