I didn't know this. I thought you had to boot off external media in order to revert back the root filesystem snapshot or make the necessary changes in /etc/fstab . I just did this test in a F33 VM: - mounted btrfs in /mnt, took snapshot of root as root.20201230 - dnf update (a bunch of updates) - rebooted - mounted btrfs in /mnt, renamed root to root.old, created new snapshot called root off root.20201230 (just the steps you mentioned) - rebooted While booting a get an error "Failed to start Load Kernel Modules" and "A start job is running for /dev/zram0". The systemd-modules-load.service show some errorrs looking up aliase named fuse, msr, platform-integrity etc... It eventually booted fine but the issue remains in further rebots (kernel module error and zram issue). So apparently there are still some loose ends doing this in-place snapshot reversal of the root filesystem? This was just a test on a scratch VM so no need to troublshoot it further.
