SUSE Cranks Enterprise Linux to 12
A lot of things have changed on the Linux Planet since 2009, when SUSE Linux Enterprise Server 11 first debuted. Today SUSE announced the general availability of SUSE Linux Enterprise 12 and it builds in new technologies and provides users with up to 13 years of extended support.
The very first line of the what's new section in the release notes for SUSE Linux Enterprise 12 is not about new features, but rather it's about security - and specifically the recently disclosed ShellShock BOURNE shell vulnerability.
"Given the proximity of the SUSE Linux Enterprise 12 release to the publication of the "shellshock" series of vulnerabilities in the GNU Bourne Again Shell (bash), we want to provide customers with information on the fix status of the bash version shipped in the SLE 12 GA release," the release notes state (the bugs are all fixed).
As is the case with other large enterprise distros, SUSE Enterprise Linux 12 used systemd instead of the older init scripts. There has also been a shift away from MySQL and instead support for MariaDB is the default.
There is also an improved installer that will help administrators to get all the required maintenance updates as part of the initial installation.
Perhaps the most interesting addition is the baked in support for Btrfs. SUSE has offered various forms of Btrfs support in recent years but in SUSE Linux Enterprise Server 12 it is a full integrated feature. Btrfs enables administrators to rollback to a known-good state if troubles occurs, thanks to the built-in snapshotting feature.
Btrfs isn't the only supported filesystem though as XFS, which is now the default in Red Hat Enterprise Linux 7, is also supported. SUSE is offering XFS as the filesystem for data, while Btrfs is the core default filesystem for the operating system itself.
Linux Containers (LXC) are supported, though Docker is only considered to be a technology preview at this point.
"Given their competitive cost pressures, IT organizations today have a hard time responding quickly to changing business needs and leveraging innovation," Nils Brauckmann, president and general manager of SUSE said in a statement. "SUSE Linux Enterprise 12 helps enterprises stay agile, reclaim budget and easily leverage future open source innovation, helping them compete more effectively now and in the future."
