And you forget that one method of recovery is to format "/" and install again, because the data is safe on "/home".
well, that is a bit of a simplification.
/home do not hold only user data, it holds also application metadata (configs, some logs...) that can't be safely shared between distros, even distro versions.
So What I do and advise most people to do at least on personal computers (=used mostly by only one people) is to have root (/), /home and some sort of /data.
Only /data holds really data, that is text files, photos, videos... and should have it's own partition.
Yes, that's one step further :-)
in this context, having / and /home on the same partition is perfectly correct an I do it often.
I also seems to remember a mail exchange where it was said that BTRFS can mirror itself to an other disk as sort of backup.
I'm also pretty sure that most of this discussion could be avoided if the features where correctly shared and documented, preferably on the openSUSE wiki (or btrfs one, not on Arch one). And this can only be done by people that make the changes as nobody else knows what happen.
Right.
For example, Richard states that BTRFS can make incremental backup much better. I trust him. But how, where is the doc? Is this page still uptodate (one year old) https://btrfs.wiki.kernel.org/index.php/Incremental_Backup ? One year ago I gave up using it.
for years openSUSE set root as btrfs and /home as XFS, and it's my present config for at least 3 years (was before leap). I don't see how I can change it without a fresh install?
You can not. In fact, arguably you can not upgrade from Leap 42.x to Leap 15.x when using btrfs on "/", because its layout has changed. Now, if there were a tool that would create a btrfs partition with all the needed subvolumes automatically, in the layout (with corresponding fstab prototype) needed for each specific openSUSE release... Even a script... things would be a bit different. -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)
