“Yesterday we reported that Ubuntu 10.10 gained Btrfs
installation support and since then we have been trying out this
Btrfs support in Ubuntu “Maverick Meerkat” and have a fresh set of
Btrfs benchmarks to serve up.“While it’s been reported that Btrfs may be the default
file-system in Ubuntu 10.10, so far this is not the case and
chances are it will not be until Ubuntu 11.04 (or even Ubuntu
11.10) that it will replace EXT4 as the default file-system. The
Btrfs file-system has been supported within Ubuntu for as long as
it’s been in the mainline Linux kernel, but with Ubuntu 10.10 there
is finally support within Ubuntu’s installer for setting up the
root file-system as Btrfs (right now though you need a separate,
non-Btrfs /boot file-system). Fedora was the first major Linux
distribution offering this functionality but since then MeeGo has
pulled in the support and has even used this Oracle-sponsored
file-system as their default. Btrfs has also being utilized by
openSUSE.“As of right now the Btrfs file-system support is not found
within Ubuntu’s Ubiquity installer found on the LiveCD, but you
must be using Ubuntu’s alternate CD with the Debian text installer
to find the Btrfs file-system support when manually partitioning
the disk. Hopefully within the Ubuntu Maverick development cycle we
will still find manual Btrfs installation support via
Ubiquity.”
