Foreword

Clear Linux OS for Intel® Architecture was designed a long time ago to fill a major gap in the existing Linux OS ecosystem. The problem identified was that Linux OS distributions were either updated once or twice a year, or the distro turned your system into a dependency hell because it allowed your package management system to combine incompatible components.

Clear Linux OS attempts to solve this problem by preventing you from combining fundamentally incompatible components, and allowing you to update with a frequency of several times a day, if needed. This allows users to receive smaller updates and maintain functional software without the overhead of dealing with software incompatibilities.

Over the last few years, the Clear Linux OS team has consistently delivered this in a usable form and we've used Clear Linux OS as a vehicle to deliver much more technological advancement to users. We've also allowed people to use our tooling to do exactly the same, without recreating Clear Linux OS from scratch. Our tooling, concepts, and content are modular and Free (as in beer and speech), and we have published everything.

The tooling covered in this training reproduces what the Clear Linux OS team develops and uses to create and maintain the OS. The tooling allows users to create a derivative OS that is based on Clear Linux OS in various degrees of similarity. Either the derivative can be entirely new and use only the tooling provided, or the derivative can contain only minor changes.

The training revolves around mixer from start to finish, and makes several segues into more advanced topics that are relevant for the whole picture. In all details, we show in precise ways how the actual deployment of the results of the advanced topics can be pushed to actual target OS installations.

About this document

This training document is a living training that will be adopted in the future to adjust for changes in the tooling and options, as well as any fixes that must be included.

The content itself is designed to be self-contained and allow someone to use a clean Clear Linux OS installation to do the training in its entirety. There should not be a need to install third party software, and the training material should explain all the concepts without the need for external reference documentation. It is expected that people will consult manual pages where appropriate.

Due to the nature of the Clear Linux OS tools, a functional network connection is required to use many of the tools. While it is possible to create a set of trainings that would function entirely offline, this would be time consuming and out of date almost immediately.

This training is hosted on github. We appreciate any feedback and comments, especially in the form of Pull Requests. Please visit the project page to open a ticket or clone/branch the training and help us.

how-to-clear

For the convenience of students, we've included a folder called files and added most of the files that need to be created or downloaded during the training exercises. This allows students to skip through some of the steps and get the proper files in place quickly and stay focused on the topic without spending time on meta-problems.
