Immutability for Easier Management of Containers and Virtual Machines

SUSE has announced SUSE Linux Enterprise Micro 6.0 (SLE Micro 6.0), the latest version of its operating system designed for containers and virtualization, aiming to make it easier to maintain. Those familiar with openSUSE Leap Micro and ALP can get an idea of the approach of this new operating system. However, following the company's lead, we'll outline the most important points.

First, SUSE Linux Enterprise Micro 6.0 is an immutable operating system that supports transactional updates. This implies the use of Btrfs as a file system along with Snapper and transactional-update, the atomic update system used by the chameleon ecosystem. The company explains that this "ensures system consistency with rollback capabilities, which is crucial for maintaining stability across container deployments."

Other features of the system include automated configuration with Ignition and Combustion, and it can now be booted in the cloud, streamlining the deployment process in both physical and virtual environments, and improving configuration efficiency for various container management systems.

Cockpit is also included, providing a web-based, user-friendly management interface that allows administrators to manage the system directly from a web browser, which is especially useful in distributed environments.

SUSE Linux Enterprise Micro 6.0 supports standalone container deployments for contexts where the complexities of Kubernetes are not required. Additionally, it can function as a fully supported host for KVM, the well-known module that allows the Linux kernel to act as a hypervisor and thus run virtual machines.

Moreover, SLE Micro 6.0 can seamlessly work with Kubernetes management tools like SUSE Rancher Prime and Kubernetes distributions such as RKE2 and K3s. The operating system's architecture is designed to serve as a Kubernetes host, providing a secure and stable platform for clusters of the well-known container orchestrator, along with support for other similar solutions like Docker Swarm.

Security-related features include integration and encryption based on TPM2, strict compliance with requirements to ensure that the infrastructure meets current data protection regulations, as well as support for new data encryption technologies that cover both guest and host credentials and the completion of certifications with the new version of SUSE Manager. The goal is to help organizations maintain data sovereignty, including in cloud and multi-tenant environments.

Finally, the improvements extend to support for containers, virtualization, and a real-time kernel designed to work with minimal latency, aimed at applications requiring immediate data processing.

All the details about SUSE Linux Enterprise Micro 6.0 are published on the company's blog, and the system is available with a trial version in its respective download section.

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
