The #NetBSD Project offers a live image for AMD64 that includes X11 and features persistence. Why does nobody ever talk about this? I put this image on a USB drive, booted it, logged in as root (no password needed), created a user account, started X, configured the network, and i everything was still there after a reboot. https://cdn.netbsd.org/pub/NetBSD/images/11.0/NetBSD-11.0-amd64-live.img.gz
