1. Why AlmaLinux OS 10.2?

In today’s fast‑moving IT landscape, stability, predictability, and security are non‑negotiable. AlmaLinux OS 10.2 offers a 100 % binary‑compatible drop‑in replacement for Red Hat Enterprise Linux (RHEL) and, by extension, for the former CentOS Stream ecosystem. It delivers a free, open‑source operating system that satisfies the exacting standards of enterprise workloads while preserving the flexibility and innovation that the Linux community prizes.

Key value propositions

If your organization values predictable operations, cost efficiency, and community‑driven development, AlmaLinux OS 10.2 is the strategic foundation for your server, cloud, and container workloads.

 

2. Core Highlights of the 10.2 Release

AlmaLinux OS 10.2 builds upon the solid base of RHEL 9, integrating a suite of enhancements aimed at modern data centers.

2.1 Updated Kernel – 5.14 LTS

• Improved hardware support – New drivers for ARM v8, Intel Xeon Scalable (4th Gen), and AMD EPYC 7004 series.
• Enhanced security modules – Integrated Spectre/Meltdown mitigations and eBPF hardening.
• Performance gains – Optimized scheduler for high‑throughput I/O and low‑latency networking.

2.2 Expanded Runtime Libraries

• Python 3.11, Node.js 20, PHP 8.2, and Ruby 3.2 are now part of the default repositories, enabling developers to deploy contemporary stacks without third‑party repos.

2.3 Container & Cloud‑Native Readiness

• Podman 4.5 and Buildah 1.29 ship with rootless support out of the box.
• OpenShift‑compatible container images for faster migration to Kubernetes platforms.
• CNCF‑certified tools (e.g., cri-o, kubelet) included in the “cloud” repository.

2.4 Security‑First Stack

• SELinux stays in enforcing mode by default, with an expanded policy set.
• OpenSSL 3.1 and GnuTLS 3.8 for modern TLS workflows.
• Automatic system-wide CVE notifications via the integrated AlmaLinux Advisory Service.

2.5 Improved System Management

• systemd 253 enhancements: hierarchical unit templates, improved transient unit handling.
• Cockpit 3.1 provides a web‑based UI for real‑time monitoring, user management, and storage configuration.

 

3. Installation & Upgrade Pathways

3.1 Fresh Install

AlmaLinux OS 10.2 is available as:

The installer follows the familiar Anaconda UI, offering both graphical and text‑mode workflows. Advanced users can leverage kickstart files for fully automated deployments.

3.2 In‑Place Upgrade

For existing AlmaLinux 8.x or CentOS 7/8 installations, the almalinux-deploy script simplifies the upgrade:

# Install the upgrade script

sudo dnf install -y almalinux-release

# Execute the upgrade

sudo almalinux-deploy –target 10.2

The process:

1. Repository conversion – Existing repo files are swapped for AlmaLinux 10.2 mirrors.
2. Package synchronization – All packages are refreshed to the latest binaries.
3. System validation – Pre‑ and post‑upgrade checks ensure services remain operational.

Tip: Always snapshot VMs or perform a full backup before initiating an in‑place upgrade.

 

4. Compatibility & Ecosystem Support

AlmaLinux OS 10.2 guarantees binary compatibility with Red Hat Enterprise Linux 9.2. This means:

• Enterprise applications – Oracle Database, SAP NetWeaver, Microsoft SQL Server on Linux run unmodified.
• Management tools – Red Hat Satellite, Ansible Tower, and Spacewalk integrate without additional configuration.
• Hardware vendors – Certification from Dell, HPE, Lenovo, and Supermicro for server platforms.

Third‑Party Software
All software packaged in the EPEL (Extra Packages for Enterprise Linux) repository is fully available, extending the ecosystem with over 13 000 additional packages.

Container Registries
Official AlmaLinux images are hosted on Docker Hub (almalinux:10.2) and Quay.io, complete with both Slim and Minimal variants to suit different footprint requirements.

 

5. Performance & Security Enhancements

5.1 I/O Optimizations

• XFS now supports delayed allocation and improved parallel write handling.
• Btrfs is optional for experimental deployments; it includes subvolume snapshots and send/receive capabilities.

5.2 Network Stack

• QUIC support in systemd-resolved for faster DNS resolution.
• TCP Fast Open enabled by default for low‑latency connections.

5.3 Security Hardening

These improvements deliver measurable gains in throughput (up to 15 % on I/O intensive workloads) while maintaining the rigorous security posture required for regulated industries.

 

6. Long‑Term Support (LTS) & Release Cadence

AlmaLinux OS follows a 10‑year support lifecycle, mirroring RHEL’s policy:

New point releases (e.g., 10.3, 10.4) are scheduled every six months, delivering back‑ported bug fixes and targeted improvements while preserving ABI stability.

 

7. Migrate from CentOS with Confidence

7.1 The “AlmaLinux Migration Tool”

CentOS users can transition in minutes using the almalinux-migration utility:

sudo dnf install -y almalinux-release

sudo almalinux-migration –from centos

The tool performs:

• Repository re‑pointing to AlmaLinux mirrors.
• GPG key replacement to validate package signatures.
• Systemd service verification to ensure boot compatibility.

7.2 Migration Checklist

With the migration tool, organizations retain application consistency, operational continuity, and cost savings—all without the need for contract renegotiations.

 

8. Enterprise Support Options

While AlmaLinux OS is free to download and use, enterprises often require dedicated assistance. Our ecosystem offers three tiers:

All paid tiers are vendor‑agnostic, allowing you to pair professional support with internal DevOps teams.

 

9. Community & Contribution Model

AlmaLinux is governed by the AlmaLinux Foundation, a nonprofit organization that ensures the distribution remains community‑driven and transparent. Contributors include:

• Independent developers – Submit patches, create documentation, and maintain packages.
• Cloud providers – Offer optimized images and integrate AlmaLinux into marketplace offerings.
• Educational institutions – Use AlmaLinux as a teaching platform for Linux system administration.

Yes. All RPM packages are built from the same source code as RHEL 9.2, guaranteeing identical binaries, libraries, and ABI signatures.

Q2 – Can I run proprietary software (e.g., Oracle Database) on AlmaLinux?
Absolutely. Vendors certify their binaries against RHEL; because AlmaLinux mirrors RHEL’s binaries, they run without modification.

Q3 – Does AlmaLinux provide kernel live‑patching?
Yes. The kpatch utility is available in the almalinux-kernel-livepatch repository, enabling zero‑downtime security patches.

Q4 – How does AlmaLinux handle SELinux policy updates?
The OS ships with the latest SELinux policy packages aligned with RHEL; updates are delivered via standard dnf channels and do not require manual intervention.

Q5 – What is the difference between the “Standard” and “Premium” support tiers?
Standard offers 24 × 7 email/ticket support with an 8‑hour SLA. Premium adds a dedicated account manager, on‑site assistance, custom kernel builds, and extended LTS beyond the default 10‑year window.

Q6 – Is AlmaLinux suitable for container orchestration platforms like OpenShift?
Yes. The distribution passes OpenShift’s certification tests and includes the required containers and runtime components (Podman, CRI‑O, kubelet).
