Oracle Linux 9.4 Available with Almost Everything from RHEL and Its Unbreakable Kernel

-


 Enterprise Linux (RHEL), we actually have to talk about four. The last one, in fact, is the oldest of the remaining ones. We're talking about Oracle Linux 9.4, and these are its new features.

Or rather, we should say that these are the new features of Red Hat Enterprise Linux 9.4, which we reported on last week. All subsequent versions are derived from it, including this one. With one caveat: Oracle Linux is generally the clone most closely aligned with the upstream source, although this concept has been distorted by Red Hat's recent moves.

Thus, in the releases of AlmaLinux 9.4 and Rocky Linux 9.4, we highlight the new "blend" both distributions used to bring these versions to life since the previously used sources are no longer available. In short, these versions are now based on CentOS Stream code, each with its own approach to building the system. And there are significant differences between them.

As for EuroLinux 9.4, it wasn't quite clear how they did it, and the same goes for Oracle Linux 9.4, despite not specifying it. It is expected that they might have done it differently. At least until the OpenELA project firmly establishes its foundation, everyone is doing things their own way, with CentOS Stream as the common denominator.

Without explicitly stating it, this is how Oracle Linux 9.4 is presented in its launch announcement, promising binary compatibility with applications, i.e., the Application Binary Interface (ABI), the only gateway Red Hat left open after the changes applied to the distribution of Red Hat Enterprise Linux code. Perhaps we should stop calling these derived systems clones?

Be that as it may, the fact is that the new features of Oracle Linux 9.4 closely mirror those of RHEL 9.4, including security improvements and updates in the software and tools chain, with the addition of the indispensable Unbreakable Enterprise Kernel 5.15 for x86_64 and aarch64 architectures, along with an option for a RHEL-compatible kernel, exclusively for x86_64.

It is worth noting that this release has seen the most new features, both in the system creation process for each of the mentioned derivatives and in the offering itself, with AlmaLinux and Rocky Linux focusing on the desktop (EuroLinux typically separates this edition from the main one). However, the Unbreakable Kernel of Oracle Linux remains a long-standing hallmark of the system.

systemd 256 arrives with run0, the ‘sudo clone’ that aims to improve security

systemd 256 arrives with run0, the ‘sudo clone’ that aims to improve security systemd 256 is now a reality, featuring an interesting innovation that could represent a significant change in Linux in the not-too-distant future, although this will ultimately depend on the decisions made by various distributions. Without further delay, let’s go over the main new features. First, we have the introduction of run0, a kind of clone of sudo that aims to enhance security by reducing the attack surface. According to Lennart Poettering, the creator of systemd, this is achieved by ensuring “the target command is invoked in an isolated execution context, freshly forked from PID 1, without inheriting any context from the client,” making its behavior more akin to SSH. And since we’ve mentioned SSH, there’s the systemd-ssh-generator , which has been added to detect if the SSHD binary (the SSH daemon) is present and then link it through socket activation per connection to various sockets depending on

Kubernetes 1.30 Available, New Version of the Container Orchestrator

-

Kubernetes 1.30, named “Uwurnetes,” has been released as the new stable version of the well-known container orchestrator, which originated at Google and is now under the umbrella of The Linux Foundation. The developers have described this release as "the most beautiful" in the history of the software and have announced it includes a total of 45 new features, with 17 in stable phase, 18 in beta, and 10 in alpha. However, here we will only mention the most important ones. The first notable update in Kubernetes 1.30 is the stable release of the Robust VolumeManager rebuild after restarting the kubelet. This involves a refactoring of the volume manager that allows the kubelet to complete additional information on how existing volumes are mounted during the kubelet's startup. Generally, this makes volume cleanup more robust after restarting the kubelet or the machine. Also arriving in stable phase is the prevention of unauthorized volume mode conversion during volume restora

Fedora Asahi Remix 40, the new version of Linux for Apple Silicon

-

  Fedora Asahi Remix 40 has been announced as the latest version of the Fedora-based system designed to run on Mac computers with Apple Silicon processors. This version primarily represents an evolution of what was already present, which is quite significant given the project's potential to enhance the Linux desktop experience, particularly in areas like sound. According to Fedora Magazine, Fedora Asahi Remix is developed through close collaboration between the Asahi Linux team and the Fedora Asahi Special Interest Group (SIG). It's worth noting that Asahi Linux is not a traditional distribution but rather a technology platform that enables running Linux on Apple Silicon processors. However, this doesn't stop its Fedora remix from being a reference system. As expected, Fedora Asahi Remix 40 is based on Fedora 40 and uses KDE Plasma 6 as its desktop environment. Therefore, the Wayland session should be the default, especially given the strong support this system has for th
