I do not think it interferes.

I am not sure to understand what you mean.  I should have missed such
discussions.  Do you have pointers?

I am sorry, I do not understand your point.  On Debian, fresh user:

--8<---------------cut here---------------start------------->8---
$ ls -a
.  ..  .bash_logout  .bashrc  .profile
$ which guix
/usr/local/bin/guix
$ guix pull
[..]
hint: Consider setting the necessary environment variables by running:

     GUIX_PROFILE="/home/kikoo/.config/guix/current"
     . "$GUIX_PROFILE/etc/profile"

Alternately, see `guix package --search-paths -p "/home/kikoo/.config/guix/current"'.


hint: Run `guix pull --news' to read all the news.

hint: After setting `PATH', run `hash guix' to make sure your shell refers to
`/home/kikoo/.config/guix/current/bin/guix'.

$ guix pull # again
nothing to be done

hint: Run `guix pull --news' to read all the news.

hint: After setting `PATH', run `hash guix' to make sure your shell refers to
`/home/kikoo/.config/guix/current/bin/guix'.
--8<---------------cut here---------------end--------------->8---

Is your point that:

   guix install hello

will install ’hello’ from the Guix at version of ’/usr/local/bin/guix’?
Well, if you see improvements in this area, please open a separate
bug/whishlist report.


All the best,
simon
