Fedora not to switch to Btrfs in version 16
Developer Josef Bacik, who contributes to Fedora and Btrfs for Red Hat, has announced that the experimental Btrfs won't become Fedora 16's default file system. In early June, the Linux distribution's Engineering Steering Committee had decided to switch from Ext4 to Btrfs, but also vaguely stipulated various requirements Btrfs was to meet before the switch; the requirements were only specified later on.
Recently, it became apparent that Btrfs has not met the stipulated criteria. The main reason for this continues to be the still ongoing development of a decent program for testing and repairing Btrfs file systems. Bacik had previously hoped that such a program would be released in May; now, the developer has mentioned a time frame of "a few weeks", but has also said that the developers' target is the Linux Plumbers Conference, which will start on 7 September. The Fedora project will probably make a second attempt to switch in Fedora 17.
