As a security guy, I approve of defense-in-depth, which is why I like Silverblue. I’m a recent but dedicated convert to Silverblue, which I run on my main home laptop, and which I’ll be putting onto my work laptop when I’m due a hardware upgrade in a few months’ time. I wrote an article about Silverblue over at Enable Sysadmin, and over the weekend, I moved the laptop that one of my kids has over to it as well. In terms of usability, look, and feel, Silverblue is basically a version of Fedora. There’s one key difference, however, which is that the operating system is mounted read-only, meaning that it’s immutable.
