After install create sys-usb-dvm?

so I installed rc1, but setup sys-net for USB, I’d rather have a sys-usb, as seems U2F doesn’t know how to use sys-net, etc

Is this complicated or can someone point me to whether this is wise or howto?

I can just reinstall, though not my 1st choice

maybe this? or is there more to it for rc1 ?

maybe that isn’t going to do the needed qrexec, so

?
edit: i’ll just reinstall correctly, …
