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?
