To enable rollback with snapper it is necessary
Thanks for that info. It gives me something to look at. Except I'm not certain what is meant by #1 and #2. How do I verify this? Or would these be the case when the disk was set up by the openSUSE Tumbleweed install?
1. Your root subvolume should be one of snapper snapshots 2. default-subvolume should be set to your root subvolume 3. SUSE_BTRFS_SNAPSHOT_BOOTING="true" should be set in /etc/default/grub 4. grub2 should be reinstalled with new setting (really reinstalled, not just configuration) - "update-bootloader --reinit"
This is in addition to normal configuration like having @/.snapshots subvolume that is mounted as /.snapshots.
I see this from mount on a system with snapper set up: /dev/sda2 on / type btrfs (rw,relatime,space_cache,subvolid=259,subvol=/@/.snapshots/1/snapshot) /dev/sda2 on /.snapshots type btrfs (rw,relatime,space_cache,subvolid=258,subvol=/@/.snapshots) So I should see the pretty much same on my mystery machine, I guess?
