OSTree

libostree (previously OSTree) is a system for versioning updates of Linux-based operating systems.[1] It can be considered as "Git for operating system binaries". It operates in userspace, and will work on top of any Linux file system. At its core is a Git-like content-addressed object store with branches (or "refs") to track meaningful file system trees within the store. Similarly, one can check out or commit to these branches.

This article is about the system for versioning updates of Linux-based operating systems. For the data structure that is a variant of the binary search tree, see Order statistic tree.

Layered on top of that is bootloader configuration, management of /etc, and other functions to perform an upgrade beyond just replicating files.

It is used by endless OS, Flatpak, Fedora, CentOS, Atomic Host,[2] and the GNOME continuous project for continuous delivery of GNOME components.[3]
