I work on a virtual machine generated with "guix system vm-image". Due to the recent core updates, the vm image will need to fall out of date unless it can be updated and reconfigured. Right now, the best way to reconfigure the vm image is to copy the system definition onto the image, then run guix system reconfigure.
This can be a hassle depending on the host, virtual machine manager, etc. used. I think it would be useful to copy the system configuration to the resulting system when it is generated so it can be used to keep a system up- to-date in the future. Is there something I can add to a configuration to accomplish this? I think it would be useful to others. I tried using this-operating-system, but I haven't had any luck even seeing what it contains.
