I have a dedicated computer for audio which I occasionally use on the internet via Wi-Fi. I was thinking of building another kernel without mitigations and my particular wi-fi card disabled. I still need networking to control my MOTU 8pre-ES that is directly connected to my computer via LAN to control its internal mixer via firefox.
From what I understand of how Sceptre/Meltdown work, via a live internet connection, booting to a different kernel for different purposes seems safe. Is this a correct assumption?
