Btrfs System Rollbacks In Fedora 13

Filed under
Linux

One of the benefits of Btrfs besides offering competitive performance against other Linux file-systems and SSD optimizations is its support for sub-volumes and writable snapshots. While Btrfs is still in development and is not yet used as a default file-system by any Linux distribution, Red Hat has been looking to capitalize upon the capabilities of Btrfs by introducing support for system rollbacks into Fedora. The Btrfs-based system rollback support has been a feature for Fedora 13 so with the release of the Fedora 13 Beta earlier this week we decided to further investigate this feature.

In order to benefit from this, you must, of course, be using a Btrfs root file-system. This can be setup by either converting an existing EXT3/EXT4 root partition over to Btrfs or by performing a new Fedora installation and using Btrfs -- we opted for the latter method. Btrfs is only available from the Fedora DVD versions and not the Live DVD/USB version that is limited to using EXT4. The DVD-based installer needs to be started with the "btrfs" boot argument added to the GRUB boot-loader; otherwise Red Hat's Anaconda installer will not offer Btrfs file-system support. Note that this boot parameter is now "btrfs" and is not "icantbelieveitsnotbtr" like in earlier Fedora releases.

KDE Neon Installer

  • KDE Neon Has Stylish New Install Wizard
    KDE Neon has adopted distro-agnostic Linux installer ‘Calamares’ its unstable developer edition. Calamares replaces the Canonical-developed Ubiquity installer as the default graphical installer used when installing the Ubuntu-based OS on a new machine. The stylish install wizard is already in use on a number of other KDE-based Linux distributions, including Chakra Linux and Netrunner.
  • KDE neon Inaugurated with Calamares Installer
    You voted for change and today we’re bringing change. Today we give back the installer to the people. Today Calamares 3 was released. It’s been a long standing wish of KDE neon to switch to the Calamares installer. Calamares is a distro independent installer used by various projects such as Netrunner and Tanglu. It’s written in Qt and KDE Frameworks and has modules in C++ or Python.
