Building a modular Linux OS

with multiple versions of components on different lifecycles.

Boltron is here!

We have built the first modular prototype - Fedora 26 Boltron Server!

Moving focus from packages to components

Modularity splits the Linux distribution into smaller pieces called modules.
Modules are provided in multiple streams and on independent lifecycles.

Giving users choice and packagers flexibility

Modules come in different streams with independent lifecycles.
Streams have different goals - specific version, stability, or following upstream.

Module as an ultimate build recipe

Packagers decide how to build - by defining components, build order, and buildroot.

Packagers decide what to ship - by filtering unnecessary binary packages.

Packagers decide how to use - by defining a supported API and install profiles.

Modules run almost everywhere

Each module can be built into multiple artifacts.
Containers for clouds and servers, flatpaks* for desktop, RPMs for tradition.

* Flatpaks are more future than the other two, but on the list!
