OSTree is a tool that combines a "git-like" model for committing and
|
|
downloading bootable filesystem trees, along with a layer for deploying
|
|
them and managing the bootloader configuration.
|
|
|
|
OSTree is like git in that it checksums individual files and has a
|
|
content-addressed-object store. 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".
