I was about to ask why openSUSE Aeon when the normal Tumbleweed supports immutable mode where / is mounted read only, when I realized that they actually removed it in https://bugzilla.opensuse.org/show_bug.cgi?id=1221742 https://bugzilla.opensuse.org/show_bug.cgi?id=1221742 But I'll share my experience: I think an immutable / really is the way forward. Just the ability to roll back and boot using an older snapshot is great: I have had an update break the boot, but I have the option of running a single command to roll back while I investigate the issue. At the time the issue happened I was busy with life and I simply rolled back and used that version for three months before I had time to investigate. Strictly speaking this does not require the current / to be mounted read only, but merely requires periodic bootable snapshots be taken and these are available to be used as a read-only /.
