Distributions of operating systems produced by BaseALT LLC are based on our own development infrastructure Sisyphus, which is supported by the ALT Linux Development Team and BaseALT LLC.
Sisyphus is currently available for the following architectures: i586, x86_64, AArch64 (ARM64), armh, mipsel (MIPS), ppc64le, RISC-V. The process of porting it to other hardware platforms is also under way.
Sisyphus is based on software-building technologies which take into account the inter-program dependencies, as well as on tried and tested developer interaction processes. This repository allows for making a stable branch (software platform) from time to time, which is then maintained for a long time and is used as the base for building the set of Alt distributions. Similar compatible distributions are released for all hardware platforms. Repositories with binary and source packages for the supported platforms are made freely available.
ALT Linux Team is an international (mainly Russian-speaking) free software development team. The team has been in operation since 2001. The main activity of ALT Linux Team is focused on Sisyphus project, including independent repository and development infrastructure. Some members participate in developing the core components of Linux.
Since 2015 the ALT Linux Team is operating in close cooperation with BaseALT LLC. Today, all the development infrastructure is owned and supported by BaseALT LLC.
Structurally, ALT Linux Team is independent of BaseALT LLC, although many of it's employees are members of the Team. Employees of BaseALT LLC and members of ALT Linux Development Team are actively involved in international free software development projects. They hold annual conferences devoted to development and application of free software (Conference for Free Software Developers, "FOSS in Higher School" conference).
In addition to software development and building up their own repository, the team is engaged in promoting Linux, free cross-platform software and free licensing in general. The community assists the release of books under a free license.
In order to get the access to direct development of Sisyphus, it is necessary to become a member of the Team.
The procedure of joining the Team is disclosed here.
When the software products are being released, the subset of packages with closed dependencies is set aside in Sisyphus repository. This subset is moved to independent branch. Branches are also known as platforms, since they are used as the basis for generation of distributions of BaseALT LLC products. New platform is released when the old branch proves unable to provide the required new features, while keeping the backward compatibility.
The main characteristic of the branch is its stability. During the whole lifecycle the platform is cleaned of critical errors and provided with security updates. Any changes to the stable branch are done only after mandatory functional and regression testing.
ALT Platform 10 (Aronia) supports the following hardware platforms:
- AArch64 (ARMv8);
- armh (ARMv7);
Distributions based on Platform 10 are released since December 2021. The following distributions are based on Platform 10: ALT Workstation, ALT Workstation K, ALT Server, ALT Virtualization, ALT Education, Simply Linux.
