[Message part 1 (text/plain, inline)]

Hello,

Paul <paul <at> denknerd.org> reported on IRC that his guix behaved strangely.  Upon
investigation we found that the following happens (on a Guix system), when logged
in as regular user (not root):

$ readlink ~/.config/guix/current
/var/guix/profiles/per-user/dannym/current-guix
$ sudo -E guix pull
$ readlink ~/.config/guix/current
/var/guix/profiles/per-user/root/current-guix

You can also rm -f ~/.config/guix/current after that and do everything above
again and it will happen again.  It even happens when guix pull has nothing to
do.

That doesn't seem right.  We should at least try to prevent this from happening,
or warn or something.

The guix package manager that did that is:
