ostree - 2022.7-2+deb12u1 main

libostree provides a library and tools 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.
.
This package contains the executables used to manage and create
filesystem trees. It does not affect the boot process for the system
on which it is installed.
