Fedora Silverblue User Guide

Fedora Silverblue is a variant of Fedora Workstation. It looks, feels and behaves like a regular desktop operating system, and the experience is similar to what you find with using a standard Fedora Workstation.

However, unlike other operating systems, Fedora Silverblue is immutable. This means that every installation is identical to every other installation of the same version. The operating system that is on disk is exactly the same from one machine to the next, and it never changes as it is used.

Fedora Silverblue’s immutable design is intended to make it more stable, less prone to bugs, and easier to test and develop. Finally, Fedora Silverblue’s immutable design also makes it an excellent platform for containerized applications as well as container-based software development. In each case, applications (apps) and containers are kept separate from the host system, improving stability and reliability.

Fedora Silverblue’s core technologies have some other helpful features. OS updates are fast and there’s no waiting around for them to install: just reboot as normal to start using the next version. With Fedora Silverblue, it is also possible to roll back to the previous version of the operating system, if something goes wrong.

In most cases, Fedora Silverblue behaves like a standard Fedora Workstation installation, and the standard Fedora documentation can be used. This guide covers those areas where Fedora Silverblue differs from a standard Fedora Workstation, including:

The primary audience for these docs are new users, who aren’t expected to have specialist knowledge or technical knowledge about Fedora Silverblue’s internals. However, some background technical information is provided, for those who are interested and want to learn more.
