Among the key new features in the openSUSE 12.2 release is the Linux 3.4 kernel, which first debuted in May of this year. The most recent kernel release is now the 3.5 kernel, which Linus Torvalds released in July.
Andreas Jaeger, program manager for openSUSE, noted that the 3.4 kernel allows the capping of CPU usage across entire groups of processes. He added that in comparison to the openSUSE 12.1 release, the addition of Linux 3.4 provides a faster storage layer. Additionally, the Btrfs filesystem has been enhanced to enable snapshotting before updates to provide additional system resiliency.
To date, openSUSE has been focused on x86 system architectures, but that is starting to change. Jaeger noted that work is currently underway on an openSUSE 12.2 ARM version. The ARM version is expected to have its first release candidate in the coming weeks.
