"In this article we are looking at the EXT4 support
within Ubuntu as well as providing a few Linux file-system
benchmarks from a netbook-embedded solid-state drive. In this
article we have published Ubuntu benchmarks of EXT4, EXT3, XFS,
JFS, and ReiserFS file-systems.
"Committed to the Ubuntu development repositories last Thursday
were the last bits of code needed for Ubuntu to properly support
EXT4 and then appeared in Friday's daily ISO spins. This work will
also appear in the upcoming Ubuntu 9.04 Alpha 3 release. The LiveCD
and alternate/server install CDs of Ubuntu 9.04 offer the option to
use an EXT4 file-system when manually partitioning the disk. Some
other distributions like Fedora have already supported EXT4 while
it was still in development.
"Ubuntu 9.04 Receives EXT4 SupportThe EXT4 file-system option is
listed next to the other file-systems supported for installation by
Ubuntu. The EXT4 support for the GRUB boot-loader in Ubuntu 9.04
was already committed and is in place. We tested out both the
alternate and LiveCDs of Ubuntu from the January 9, 2009 daily
spins. Setting up the EXT4 file-system for the / partition worked
as expected without any issues."
