Guix can manage multiple profiles, each with their own history, and that
is what's happening here. By default, there are two profiles: the one
that deals with Guix itself, and the one that contains your installed
packages.

`guix pull` uses the former, found at '~/.config/guix/current'.

You can interact with this profile using the '--profile' argument to
`guix package`. For example:

------
$ guix package --profile=$HOME/.config/guix/current --list-generations
Generation 115  Mar 27 2020 03:05:01
  guix  260eae7 out     
/gnu/store/ynihdaa8ripvrw2mzxdslhl3av938jpp-guix-260eae789
[...]
$ guix package --profile=$HOME/.config/guix/current --switch-generation=115
switched from generation 121 to 115
------

On the other hand, when you install packages, Guix uses the default
profile, which is found at ~/.guix-profile.
