I discussed btrfs with some of our FS experts at DevConf a couple weeks ago, and then further via email after. I'm not convinced it's ready to be the default FS for any product in Fedora yet. I'm hoping that I can get some/one of these experts to attend Flock this year and give a talk on btrfs. Where it's at, what it needs to be the default fs, etc. We may wind up with a feature-reduced btrfs option in the not too distant future being viable (e.g. no multi-device spanning, no RAID).
We may want to reword the 'file system' section I just put in the tech spec, then.
I'll look it over soon. I've been trying to play catch up on kernel bugs this week.
I realize btrfs is something people are really excited about and really want, but I'm not willing to let hype or "mostly" working features swing our decision. People have been living without fs-rollback for years, and I think they can wait a bit longer. The last thing we need is to get bad hype because people start losing their data if we force the issue.
Tbh, from where I stand, people were excited about btrfs a few years ago, but the excitement has wanted. You can hold your breath only for so long. Time to either push it over the hump this year, or give up and move on. Isn't suse using btrfs by default now ?
SLES or OpenSUSE? For SLES, I think they have it as an option, but in a very reduced mode as I described above. I think it's an option in OpenSUSE 13.x, but it isn't the default because there were things they didn't think were production ready. So they basically match Fedora in terms of defaults. I do think they promote and work on snapper and btrfs more than we do though.
