Connecting via broadband connection impossible before installation of Guix

[MorphicResonance]

Forgotten about broadband connection during operating system installation (as usually with official linux iso).

If you are with 3g modem and mobile broadband connection it is not possible to make Guix install. How about including packages/drivers to create mobile network connections active before the final installation phase?
It is good to have an iso which is focused on creating internet connection by any possible methods first because without it you can't install this OS. For supporting mobile broadband connection iso should include such packages as usb-modeswitch ,NetworkManager, mobile-broadband-provider-info, ModemManager
