> Guix and its dependencies when doing ‘guix pull’, which brings us closer
> to what the ‘guix’ package provides.
> Thus we can at least partly address the issue described in

> ‘guix pull’ install not just a bunch of .go files but also guile-git,
> guile-ssh, gnutls, and Guile itself.
> To do that, we need a “paradigm shift” (sounds cute, no? :-)).
> Currently, ‘scripts/guix’ fiddles with its %load-path and adds
> ~/.config/guix/latest if it exists.  The new ‘guix pull’ should provide
> not just .go files but also a ‘guix’ command referring to the latest
> Guile, Guile-Git, etc.
> To achieve this, I think the new approach would be to have:
>   export PATH=$HOME/.config/guix/current/bin:$PATH
>   export INFOPATH=$HOME/.config/guix/current/share/info:$INFOPATH
> ‘guix pull’ would update ~/.config/guix/current, which would contain the
> ‘guix’ command, all the .go files, locales, the Info manual, and ideally
> ‘guix-daemon’ as well.
> ~/.config/guix/current could be a profile, or something that resembles a
> profile.
> For a while ‘guix pull’ will have to keep updating ~/.config/guix/latest
> as well, for users running an old ‘guix’ command.

First thought: Woo! Good progress!
On your propossed steps, sounds good to me.
