I did use Fedoral Silverblue for a few months, but eventually decided it was about the same amount of work as using a fully siloed system like Tails or a build everything system like BSD. That's my bias showing, I suppose, but I have a lot more experience and control with source code distributions. I used Gentoo Linux and macOS heavily for many years. I worked on FreeBSD chroot jails for a couple of years as well. I actually don't have much experience with other people's container systems; cgroup-based containers always felt like FreeBSD jails and granular access control lists. Lots of experience with ACL-based security from Windows NT systems or even Banyan Vines. So podman/docker are great, but I was more comfortable rolling my own. Which is a very long way to say: I am crazy, and Fedora Silverblue is worth trying.
