Description:
content-addressed filesystem for operating system binaries (library)
libostree is a library for managing bootable, immutable, versioned filesystem trees. It is like git in that it checksums individual files and has a content-addressed object store; unlike git, it "checks out" the files using hardlinks into an immutable directory tree. This can be used to provide atomic upgrades with rollback, history and parallel-installation, particularly useful on "fixed purpose" systems such as embedded devices. It is also used by the Flatpak application runtime system. . This package contains the shared library.
