platform, and optimized for Intel's microprocessors with an emphasis on performance and security. Its optimizations also affect AMD-systems. Clear Linux OS follows a rolling release model. Clear Linux OS is not intended to be a general-purpose Linux distribution; it is designed to be used by IT professionals for DevOps, AI application development, cloud computing, and containers.

History

In 2015, Intel introduced ''Clear Linux OS'' at OpenStack Summit 2015, Vancouver initially, it was limited to cloud usage. Intel began the ''Clear Containers'' project to address container security. In 2015, originally, ''Clear Linux OS'' was deployed as a single monolithic unit. In May 2019, Clear Linux OS released a new Desktop Installer and started a Help Forum. ''Clear Linux OS'' is available via Microsoft Azure marketplace, and Amazon Web Services marketplace.

Features

Clear Linux OS uses reference stacks to install images that are optimized and tested together for specific use-cases. It also utilizes a strict separation between User data and System config files, called ''stateless'', so that even a misconfigured system will still boot correctly and then perform a factory reset so it can be reconfigured.

Desktop

Package management

Packages are usually installed and updated through bundles with the help of swupd, which is described as an ''OS-level software update program'', using delta updates to minimize update size. Flatpak is also preinstalled and can be used to install and use packages. Mixer is the tool for creating 3rd-party-bundles, which can then be installed using swupd.
