The loss of data stored on the rootfs is more of an inconvenience (downtime) than something serious (permanent data loss). Consequently, the data stored elsewhere (e.g. /home) is far more important. If SUSE thought btrfs was stable enough, they would use btrfs for /home.
The last that I checked, SUSE used XFS for /home and others are saying the same here.
Given that you seem to have registered solely for the purpose of posting replies to me, would you care to say who you are in a manner that can be verified and provide citations, or do you just intend to troll?
(Interestingly, they use XFS for /home)
