UDS is over! And in the customary wrap-up I stood up and told the audience what the Foundations team have been discussing all week. One of the items is almost certainly going to get a little bit of publicity.
We are going to be doing the work to have btrfs as an installation option, and we have not ruled out making it the default.
I do stress the emphasis of that statement, a number of things would have to be true for us to take that decision:
- btrfs would need to not be marked “experimental” in the kernel config; we understand that this is planned for 2.6.35, which is the kernel version we are expecting to ship in Maverick.
- btrfs is not currently supported by GRUB2 (our boot loader) or the installer; these pieces would need to be finished before Feature Freeze.
- If that happens, we may make it the default for Alpha releases to gain testing; that testing must go smoothly.
- The btrfs upstream must be happy with the idea.
- We must be happy with the idea.
It’s a tough gauntlet, and it would only made with the knowledge that production servers and desktops can be run on Lucid as a fully supported version of Ubuntu at the same time. I’d give it a 1-in-5 chance.
