Linux users: remember that you’re not using a Linux box, you’re using a Windows box, or a Chrome box, and reinstalling an OS, which the OEM doesn’t support, so they won’t be offering you any way to update your firmware with that OS. Unless you’re buying your machine from an OEM that installs Linux. If you are a Linux user, stop buying Windows/Chrome PCs and buy Linux PCs.
