Linux Top 3: Linux 3.4 Goes Stable, Fedora Delayed and LinuxCon Opens the Cloud
It has been another busy week on the LinuxPlanet, with big kernel news last week as the momentum and excitement now builds in the lead up to this week's big LinuxCon event.
1) Linux Stable Kernel release
The stable Linux kernel is a precious thing. The rapid rate of Linux kernel development means that we all see new bleeding edge kernels every few months, which is great for innovation. The practical reality is that not everyone or every system can or needs to stay on the kernel release treadmill – that's where the stable kernel comes into play.
The stable kernel has a longer maintenance cycle that can be two years in length (or in some cases, even longer). This past week, Linux Foundation Fellow, Greg Kroah-Hartman clarified which kernels will now be considered for long term support.
"As I'm getting a few questions about this, and I realized that I never sent out an email about this, yes, the 3.4 kernel tree will be the next -longterm kernel that I will be maintaining for at least 2 years," Kroah-Hartman wrote in a mailing list posting.
The 3.4 kernel was first released in May of this year. Among the noteworthy improvements that debuted in 3.4 are improvements to Btrfs as well as increased scalability for the number of virtual CPUs that KVM can support.
The 3.4 kernel is not the only long term kernel that Kroah-Hartman is currently committed to maintaining. He currently also has pledged to keep the 3.0 kernel tree maintained for another year. Linux 3.0 was released in July of 2011, including Xen Hypervisor integration.
While Kroah-Hartman is still maintaining the 3.0 and 3.4 kernels, the Linux 3.5 kernel is not as fortunate. He noted that the 3.5 will only be maintained until the 3.6.1 kernel is released. Linux 3.5was only released at the end of July. Linux 3.6 is still at the release candidate stage and isn't expected to be generally available until early September.
2)Fedora 18 Delayed
In the Fedora Linux community, small delays in a release cycle are not all that uncommon. In an effort to ensure quality, the release date can slip by a week or more. That's the case with the upcoming Fedora 18 release which is now one week off its initial schedule.
"Today at Go/No-Go meeting it was decided to slip Fedora 18 Alpha release by one week due to numerous unresolved bugs and incomplete test matrices for Alpha," Fedora developer Jaroslav Reznik wrote in a mailing list posting last week.
Fedora 18 was originally set for release on November 11th and is now expected to be generally available a week later, on November 13th.
3) LinuxCon USA 2012
The annual Linux love-fest known as LinuxCon kicks off this week in sunny San Diego. As was the case with the 2011, the key headliner is none other than Linux creator Linus Torvalds himself.
Never a man too shy to state his honest opinion, Torvalds will be joined onstage by fellow kernel developers Greg Kroah-Hartman, Ted Ts'o, Sarah Sharp and James Bottomley.
In addition to the kernel panel, this years' event is also co-located with an event called CloudOpen, which is all about Linux and the open cloud. Among the CloudOpen speakers are OpenStack leader Jonathan Bryce as well as Eucalyptus CEO Marten Mickos.
