I would also like to add that snapshot 0117 introduced the new btrfs default subvolume layout
Any fresh installation of Tumbleweed using the default btrfs root filesystem will no longer have multiple subvolumes under /var (eg /var/lib/mysql, /var/cache, etc) and instead have a single unified /var subvolume.
This simplifies snapshots and rollbacks, will prevent accidental dataloss on rollback for any user data held in /var, and improve performance of any database or VM images that are held in /var as all of /var also now has Copy-on-Write disabled by default. It's also particularly useful for openSUSE Kubic which was struggling with the consequences of much of /var being read-only as it was considered part of Kubic's read-only root filesystem.
We will not be automatically moving user data from the old structure to the new one, but I'm open to any suggestions on how to script it if anyone has any bright ideas.
Richard, is there a documented manual way (wiki, github, ml), for those who will not do a reinstall, but would like to move to the new layout ? I'm a bit surprised about removing data checksum on /var (nocow implying this) If you have a bit spare time to point me to some material explaining the decision, I would be really interested.
