Btrfs is a new copy on write file system for Linux aimed at implementing advanced features while focusing on fault tolerance, repair and easy administration. More info, here.
Colin Watson (Ubuntu Development Manager) just announced on the Ubuntu-Devel mailing list that you can now perform installations with a BTRFS root filesystem using the latest Ubuntu 10.10 Maverick Meerkat daily ISO (only available in the alternate ISO!).
The BTRFS fileystem is only available through the manual partitioning for now. Also, you cannot boot from a BTRFS filesystem for now (although the devs are working on it) - just like I was telling you when we tested MeeGo, so you must create a separate /boot partition (ext3 or ext4) and set it as the boot partition.
Even though it seems Ubuntu 10.10 Maverick Meerkat will get BTRFS support after all, Ext4 will remain the default filesystem in Maverick.
Important: this is only available for testing purposes for now. Be very careful as it may erase all your data!
