BobbyeM71hxwUbuntu 10.10 Might Make btrfs the Default Filesystem

The next version of Ubuntu 10.10 could include btrfs as the default filesystem replacing ext4, said Ubuntu Developer Manager Scott James Remnant.

A lot has to go right between now and the Ubuntu 10.10 feature freeze before btrfs can get promoted to the default.

According to the Kernel.org Wiki, Btrfs is a new copy on write filesystem for Linux aimed at implementing advanced features while focusing fault tolerance, repair and easy administrative. Initially developed by Oracle, Btrfs is licensed under the GPL.

According to Remnant, the btrfs needs to not be marked “experimental” in the kernel config. He also added, “This is planned for 2.6.35, which is the kernel version and expecting to ship” with Ubuntu 10.10.

Currently, the new filesystem is not supported by Grub2, Ubuntu’s boot loader, or the installer. That would need to be finished, before feature freeze, said Remnant.

He explained, if that happens, we may make it the default for Alpha releases to gain testing, that testing must go smoothly. And the btrfs upstream must be happy with the idea and, we must be happy with the idea.

He put the odds of all of this working out at 1 in 5.
