I am also not sure, if Btrfs roll-backs are always working as expected.
One example: As MySQL was dropped from TW, "zypper dup" installed MariaDB as a MySQL replacement. I didn't know that, otherwise I had locked the MySQL packages. My system broke because I used MySQL specific options in /etc/my.cnf. Also I had no interest to upgrade to MariaDB on this computer.
So I downloaded the old MySQL packages from TW mirrors (and later the source-RPMS from Leap 42.3) and installed MySQL again. After downgrading to MySQL I got some problems with my /var/lib/mysql data, caused by the MariaDB upgrade scripts, which could be handled manually.
To summarize, I had problems with upgrading and downgrading packages. But how could Btrfs help here?
If the Btrfs roll-back reverts /usr/*/mysql*, /var/lib/mysql and /etc together, then I loose updated data in /var/lib/mysql - modified between the upgrade and the downgrade. If the roll-back leaves /var/lib/mysql intact, then the roll-back does not work as expected. Personally I would prefer announcements which warn the user before they may run into known problems. Sometimes such warnings can be found in the mailing lists.
Well, it is for that reason that I avoid TW... Not only that, of course. - -- Cheers, Carlos E. R.
