Indeed; applying.

Note that GUIX_PROFILE here is a shell variable, not an environment
variable.  It value matters only for the “.” that immediately follows.
After that, it no longer matters.

Isn’t it what ‘guix install’ printed rather than what ‘guix pull’
printed?

For example, look:

--8<---------------cut here---------------start------------->8---
$ guix pull -p /tmp/g
[…]
building profile with 1 package...
hint: Consider setting the necessary environment variables by running:

     GUIX_PROFILE="/tmp/g"
     . "$GUIX_PROFILE/etc/profile"

Alternately, see `guix package --search-paths -p "/tmp/g"'.


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

The hint is about this very profile, not about ~/.guix-profile.

Thanks,
Ludo’.
