(Adding bug-guix so we keep track of it.)

Good question.  We can’t do that at the moment, but it would be simple
to add.

In the meantime you can do it by hand by changing the target of the
/var/guix/profiles/per-user/$USER/guix-profile symlink (or similar.)

Thanks,

Note that commit b3bb82f1 adds the '--switch-generation' option to
'guix package'.

Indeed, I think it answers the original request.
So I’m happily closing the bug.  :-)
