We see these lines:

  [ INFO ] Installing /var/guix and /gnu...
  [ INFO ] Linking the root user's profile
  [ PASS ] activated root profile at /root/.config/guix/current

which is evidence that ~root/.config/guix/current was created and is not
a dangling symlink.  Further more, the binary tarball does contain that
.pub file:

So I don’t see what happened.

Julien, could it be that “something else” removed /root/.config or
/var/guix/profiles while it was running?  Or… any other idea?

Thanks,
Ludo’.
