On November 26, 2021, we released version 8.5 of the EuroLinux operating system. It is compatible with the latest upstream release. With this release, we focused on a smooth rebuild of the system both at our site and at organizations compiling their own systems/forks using EuroLinux Gaia system.
On November 26, 2021, we released version 8.5 of the EuroLinux operating system. It is compatible with the latest upstream release. With this release, we focused on a smooth rebuild of the system both at our site and at organizations compiling their own systems/forks using EuroLinux Gaia system. For the first time we coordinated the system build in several organizations in parallel. The experience we gained will allow us to work even faster in the future.
At the beginning of the release notes we will describe the technical advantages and new capabilities of the EuroLinux ecosystem. Then we will present the roadmap and links to the release notes documents along with the jumpstart documentation. All new features in the release are marked as (New) in the header.
Advantages and technological differentiators of EuroLinux
(New) Universal Migration Scripts
We have released universal migration scripts. They are available at https://github.com/EuroLinux/eurolinux-migration-scripts. What’s important is that these scripts update all packages of the distribution you are migrating from. No packages from the previous vendor remain after migration. This is the implementation of one of the popular requests made by our customers. In addition, the scripts have options that allow you to customize their operation to individual requirements. The migration process is described here.
(New) HA and RS Repositories
EuroLinux 8.5 is the first release that includes High Availability and Resilient Storage repositories from the beginning. They significantly increase the system’s capabilities and allow for easier migration, especially from very expensive cluster solutions from other vendors.
(New) Open x86_64 buildroot with HA and RS repositories
We have added HA and RS repositories to our open buildroots. These are available for the x86_64 architecture, as they are not present on other architectures.
Open x86_64 buildroot
To date, none of the distributions derived from Red Hat® Enterprise Linux® sources (both RHEL itself and those that try to call themselves community-developed systems) have made their buildroot open. This means that those not in the project cannot fully enjoy the privilege of building their own software on a given system. All of these systems provide repositories devoid of many packages. In particular the development packages, which contain (among other things) the headers necessary to develop your own software for Enterprise Linux platforms. EuroLinux is the only one Enterprise operating system vendor that has decided to make full build trees available to the community. These contain all packages produced from source packages contained in the repositories.
NOTE: Packages and repositories that give access to full build trees are not officially supported. For example in the case of perl packages, they are broken by design because it is impossible to simultaneously make all build artifacts available and support 100% modularity.
Below is a sample .repo file that contains addresses to certify-BaseOS-all, certify-AppStream-all, ceritfy-PowerTools-all, ha-all and rs-all for x86_64 architecture. These repositories should be used for building packages – do not use them as your main system repositories.

Open i686 buildroot
Although the 32-bit architecture is slowly becoming obsolete, a huge part of software still requires a runtime stack for 32-bit applications. What’s more, due to the growing popularity of Linux it’s actually impossible to fully abandon it, because of support for full version of Wine and computer games. This was painfully discovered by the Canonical team, which in Ubuntu 19.10 tried to abandon support for 32-bit libraries – and consequently also support for platforms such as GOG or Steam. The dissatisfaction of the community and the outflow of users was so great that it was decided to bring back 32-bit libraries.
Note: As with the x86_64 version, packages and repositories that give access to full builds are not officially supported. In the case of perl packages, they are broken by design because it is impossible to simultaneously make all build artifacts available and support 100% modularity.
Below is a sample .repo file, that contains addresses to certify-BaseOS-all, certify-AppStream-all and ceritfy-PowerTools-all for i686 architecture. These repositories should be used for building packages – do not use them as your main system repositories.

EuroLinux 9
EuroLinux 9 is also under development. The changes between versions 8 and 9 are not as large as the differences between versions 7 and 8. By analogy with other versions of EuroLinux, it is based on Red Hat® Enterprise Linux® source code, and the technical goal is to achieve 1:1 binary compatibility. Since the release date of the stable upstream version is unknown, we do not include information about the release of EuroLinux 9 in our roadmap.
Open Documentation and JumpStart
We recently created open documentation for EuroLinux. We wanted as much transparency as possible and the possibility to involve the community, which results in:
- a repeatable documentation build process – any user can build and run the documentation locally
- the possibility to submit ideas – our engineers are willing to describe topics that the community finds important and needs to be clarified
- the possibility of submitting corrections – everyone can submit their own corrections to the documentation
- the possibility to submit your own documentation to become part of the EuroLinux documentation.
The open source documentation is available at docs.euro-linux.com and is hosted on GitHub Pages. This is a new project, so the documentation is currently being incrementally added.
Package Delivery using CDN
By using a global CDN provider, packet transfer speeds have increased significantly. This is especially noticeable when dealing with heavy loads and massive downloads. In the future, we will look to expand our systems to include the ability to use community mirrors.
Gaia 2.0 (former Beast) build system
The EuroLinux build system has been enhanced with the ability to template configuration files. Now instead of 4 different files (for x86_64, i686, aarch 64 (ARM 64) and ppc64le architectures) everything is configured at the level of a single file. Customers developing their own Linux based on EuroLinux sources already have access to the latest version of the build system.
Additional improvements have been made to the build stack. We’ve added the Vardøger project (written in ASCII characters as vardoger) – which improves package comparison capabilities relative to the upstream solution.
In addition to increasing the capabilities of the build system, we made marketing changes. According to suggestions we decided to change the name of this project, because the word beast has both positive and negative connotations. During the vote the name was chosen from Greek mythology “Gaia” that is Mother Earth.
Open Core
We have modernized our software sharing model. From version 8.3, EuroLinux is available both as a paid subscription and for free in the Open Core model. The advantage of such a solution is to deliver as much value as possible to users and communities. It is a modern, transparent and responsible business model.
From version 8.3, every user of EuroLinux and EuroLinux containers receives a full system with updates released at the same time for both, paid and free users.
The paid version of the system additionally provides:
- direct manufacturer support
- access to errata files
- access to additional intermediate packages (if the support service requires so)
- impact on product development.
Complete stack – all system versions
EuroLinux is available and supported in versions 8.x, 7.x and 6.x. As a result, it can be used as the only system in an organisation’s ecosystem.
The latest supported versions of EuroLinux are:
- 8.5 fully supported system
- 7.9 fully supported system
- 6.10 the system is supported by EuroES (Extended Support – individual subscription).
Authorized training
The software, like any tool, is of little use without people who know how to use it properly. That is why we also offer authorized training in the administration of Enterprise Linux systems at various levels of advancement:
- Enterprise Linux System Administration I
- Enterprise Linux System Administration II.
In Q1 and Q2 of the 2022 we plan to provide two more training courses:
- Enterprise Linux Real Engineer
- Enterprise Linux Ansible Engineer.
The first one focuses on configuring multiple system services. After its completion, the participants will be able to find themselves in a modern environment, where many services, often closed in microservices or containers, must cooperate seamlessly together. The issues of troubleshooting and debugging, valuable from the point of view of expert knowledge, will also be discussed. This is an updated version of the Enterprise Linux 7 training. The other training is devoted to automation in Linux using Ansible technology. It is recommended, among others, for EuroTower or Ansible Tower users.
Support
In addition to delivering our own products, we also provide professional technical support. Its distinguishing feature is the simplified procedure in the first line support, allowing for quick contact with specialists (engineers and architects) of the second and third line support. In addition, we offer dedicated professional services for the client, services in the field of capacity planning, audit services, migration assistance, tuning database systems, system architect support, as well as proactive continuous care.
Errata
We provide our clients with repositories containing, in addition to packages, information about errata, i.e. about: security patches, increasing the capabilities of a given software package or fixing errors. These files are important when using EuroLinux in environments where software updates are mainly enforced by security patches.
Clear, stable plans and persistence in action
The EuroLinux project has been fully communicating its plans and their timeframe since the initial release of version 8.3. Unlike many young organizations and their branches that have emerged recently, we are not dependent on external sponsors. This allows us to be autonomous and persistent in pursuing the goal that is our company’s guiding motto: True Product – Real Support – Fair Price.
Additional modules (Add-On) included
EuroLinux is a complete solution with standard modules that are available in other distributions for an additional fee. They extend the functionality of the system and increase its technical value. Among them are: Load Balancing, High Availability and Resilient Storage.
Full software version compatibility
EuroLinux is the only modular distribution on the market whose RPM packages are 1 to 1 compatible with RHEL® releases. This required the development and implementation of a build system that allows for local and repetitive compilation of packages.
Below is an example summary for the modular nginx package:
| System | Package name | Package version | Release |
|---|---|---|---|
| RHEL® | nginx | 1.14.1 | 9.module+el8.0.0+4108+af250afe |
| EuroLinux | nginx | 1.14.1 | 9.module+el8.0.0+4108+af250afe |
| Oracle® Linux | nginx | 1.14.1 | 9.0.1.module+el8.0.0+5347+9282027e |
The topic of building modular packages, creating a build system from scratch, and a software supply-chain attack resistant operating system will be covered in detail in the near future.
Golden Key
For customers who expect technical support we offer the purchase of subscriptions. The unit price of the service not only decreases with the number of machines, but additionally from a certain level we offer Golden Key subscriptions. It enables the organization to use the software without any quantity limits.
EuroLinux Gaia – build your own Linux
The proprietary EuroLinux Gaia tool introduces a new ground-breaking functionality for organisations. It is the ability to independently build (compile) the operating system from source files in the customer’s own infrastructure. This is the highest possible level of system delivery and support. It guarantees the maximum level of security (trust) and allows customisation of the product. It also allows creation of your own dedicated distribution (fork).
As part of the solution, the customer receives:
- EuroLinux Gaia build system
- software comparison system with test oracle
- Battery Repositories, which are packages not included in the distribution, necessary for building it
- internal EuroLinux Gaia documentation for building the system
- direct support (on-site, telephone, e-mail) from a EuroLinux Release Engineer
- Golden Key subscription.
Updates for CentOS after 2021
EuroLinux is also a recommended alternative to CentOS, which will cease to receive stable updates at the end of 2021 and will become an experimental distribution. As CentOS is part of the Enterprise Linux family, it can use stable updates from EuroLinux. This process is completely safe, reversible and does not require reinstallation of the system. This makes it possible to extend the CentOS life cycle until 06/30/2029. Therefore, companies are increasingly choosing EuroLinux support, especially for environments with large numbers of systems. We have prepared a special support offer for such organisations.
