Developers of the Opensuse presented the release of the atomic updated distribution Opensuse Leap Micro 6.0. This distribution is designed for creating microservices and serves as a basic system for virtualization and container insulation platforms. For downloads, installation assemblies are available for architectures x86_64 and ARM64 (AARMH64), along with ready-made system images for virtualization systems and raw images for copying on carriers.
Opensuse Leap Micro is based on the project technologies MicroOS and is marketed as a commercial product Linux Enterprise Micro, which does not include a graphical interface delivery. Configuration can be done through the web interface Cockpit. Users can control the system via the browser using tools like cloud-init with settings transfer at each boot, or combustion for initial configuration. Users also have the option to switch quickly from Leap Micro to SUSE SLE Micro, enabling the transfer of configurations between the two products.
A key feature of Leap Micro is its atomic update mechanism, which automatically loads and applies updates. Unlike atomic updates in Fedora and Ubuntu based on OSTREE and SNAP, Leap Micro uses full-time packet management tools (Transactional-Update) combined with the Shotov mechanism in FS BTRFS for atomic switching. This allows users to roll back the system to a previous state if issues arise after updates. Live patching is also available to update the Linux kernel without restarting or interrupting work.
The root section is mounted in read-only mode during operation. Runtime Podman/CRI-O and Docker support is integrated for launching isolated containers. Micro-editing of the distribution is utilized in the ALP (Adaptable Linux Platform)
