I think I didn't intuitively understand profiles. I think I actually started using them last year (apart from the user profile) after reading the Guix Profiles in Practice recipe, which made things clearer to me (but I don't think I grok the concept).

So, right now, I see a profile like a collection of packages that you can activate/deactivate in your environment by setting the GUIX_PROFILE environment variable and sourcing its profile file.

In the Guix Profiles in Practice recipe, for example, you are instructed to set GUIX_PROFILE and then use it when sourcing the profile. So I thought it deserved an entry in the index, since it is mentioned so often when working with profiles.

I think I was expecting something like:

GUIX_PROFILE
  This is an environment variable that you can set to
  [...]. Its value is an absolute path to a Guix profile.
  See Profiles for more information.

Now I'm confused.. :)
