The issue here is that the installation media has no
~/.config/guix/current: it uses the "snapshot" Guix, from (gnu packages
package-management).  Which in turn installs an even older snapshot.

It is the same reason you got an older kernel than the installation
image: when building the image, you get the latest version (from your
~/.config/guix/current); but when installing, you get the version
contained in the snapshot.

So it's Guix all the way down.  A funny side effect is that if you never
`guix pull`, but keep reconfiguring, you'll gradually downgrade your
system one snapshot at a time.
