rpm-ostree

RPM-ostree is a command line tool used in Linux systems to manage the operating system image at a low level. It is primarily used in systems that utilize the OSTree project to build atomic, reliable, and immutable Linux tree deployments.

With RPM-ostree, users can install, update, and rollback the entire system image as a single unit, providing a convenient way to manage system upgrades and downgrades. It uses the RPM package format for software packaging and allows for the creation of image-based systems using rpm-ostree compose.

This tool also supports delta updates, which minimize bandwidth consumption during updates by only downloading and applying the changes between two versions. Additionally, it integrates with package managers, like DNF, enabling users to install and manage individual packages if needed.

RPM-ostree further enhances security by utilizing SELinux, ensuring the integrity of the system image and preventing unauthorized modifications. It provides a reliable and consistent working environment by keeping the base filesystem read-only and separating user modifications in "user units".

Overall, RPM-ostree simplifies the management of Linux system images by allowing users to control the entire system state as a single unit, providing atomic updates, rollbacks, and enhanced security measures.
