Hello List , - in case of interest : tried to get started with snapper on ext4 filesystem : Konsole output #snapper create-config / but did not work out . . . got error : Konsole output " Creating config failed (invalid filesystem type)." ............ read one needs Thin Provisioning LVM like : http://www.tecmint.com/setup-thin-provisioning-volumes-in-lvm/ ............ regards -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Yes it depends on an underlying snapshotting function being present. And it's impractical to use thick volumes. For plain ext4 or XFS and atomic updates and rollbacks, that's www.projectatomic.io. It's really a very different layout, update, and boot method though. See https://lwn.net/Articles/581811/ There's a distinction between OSTree and rpm-ostree implementations. This is well explained here https://lwn.net/Articles/581811/ How all of this shakes out, time will tell. But even now the updates are more reliable in that updates are applied to a new tree, not the current tree - so are not only atomic but aren't replacing currently active libraries; and it's a much more reliable way for multiple OS versions to share a single volume and multiboot. -- Chris Murphy -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Oops, bad paste. One of those lwn links was supposed to be this one on comparisons: https://wiki.gnome.org/Projects/OSTree/RelatedProjects -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
