No disrespect intended, but my experience is that SuSE has always played fast and loose with the filesystem defaults.

I recall they switched to reiserfs as default at one point. reiserfs was never a good choice for data consistency - the fact that storing a reiserfs image in a file on the host reiserfs filesystem and then doing an fsck on the host FS would corrupt the FS should be a clear signal that there are fundamental problems remaining to be solved.

That said, I'm playing with btrfs on some of my machines, and it seems quite nice. But no way would I risk using it on a production server at this time.

None taken. To be clear, we do provide enterprise support for ext4 and XFS as well (which a lot of people use for the reasons you mentioned). In my experience, btrfs still has some growing pains (especially when it comes to quotas, which will cause your machine to lag quite a bit when doing a balance) but is definitely serviceable as a daily driver (though for long-term storage I use XFS).

Ah, that's good to hear. It's been a while since I've used SuSE.

Of course, someone has to go first and filesystems never truly get battle-hardened until distros start pushing them. I appreciate that SuSE does this from that perspective. It means when I switch over there will be less bugs. :)

I'm using btrfs as a daily driver on my workstations so I get some experience with the tooling, and also because features like consistent snapshots are really nice to have. Still haven't taken the plunge on the server side, I expect I'll give it a few years until it's considered "boring".
