Hello, trying to use a vm with ./pre-inst-env guix system vm gnu/system/examples/bare-bones.tmpl From a branch in which I'm working on some packages When I launch the vm, the packages are not there guix package --list-available | grep my-package returns nothing On the host built them and linted them with ./pre-inst-env guix build/lint my-package from within the same branch, of course What am I missing ?
