OSTree
System for versioning updates of Linux-based operating systems
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.
