This @code{~/.config/guix/current} profile works like any other profile
created by @command{guix package} (@pxref{Invoking guix package}). That
is, you can list generations, roll back to the previous
generation---i.e., the previous Guix---and so on:
@example
-$ guix package -p ~/.config/guix/current -l
