It's unlike git in that it "checks out" +the files via hardlinks, and they should thus be immutable. Therefore, +another way to think of OSTree is that it's just a more polished +version of Linux VServer hardlinks. + +Features: +* Atomic upgrades and rollback for the system +* Replicating content incrementally over HTTP via GPG signatures and + "pinned TLS" support +* Support for parallel installing more than just 2 bootable roots +* Binary history on the server side (and client) +* Introspectable shared library API for build and deployment systems + +This last point is important - you should think of the OSTree command +line as effectively a "demo" for the shared library. The intent is that +package managers, system upgrade tools, container build tools and the +like use OSTree as a "deduplicating hardlink store". |
