# rpm-ostree: A true hybrid image/package system
|
|
|
|
rpm-ostree combines [libostree](https://ostree.readthedocs.io/en/latest/) (an image system),
|
|
with [libdnf](https://github.com/rpm-software-management/libdnf) (a package system), bringing
|
|
many of the benefits of both together.
|
|
|
|
```
|
|
+-----------------------------------------+
|
|
| |
|
|
| rpm-ostree (daemon + CLI) |
|
|
+------> <---------+
|
|
| | status, upgrade, rollback, | |
|
|
| | pkg layering, initramfs --enable | |
|

| libostree (image system) | | libdnf (pkg system) |
|
|
| | | |
|
|
| C API, hardlink fs trees, system repo, | | ties together libsolv (SAT solver) |
|
|
| commits, atomic bootloader swap | | with librepo (RPM repo downloads) |

For more information, see the online manual: [Read The Docs (rpm-ostree)](https://rpm-ostree.readthedocs.org/en/latest/)

|
**Features:**
|
|
|
|
- Transactional, background image-based (versioned/checksummed) upgrades
|
|
- OS rollback without affecting user data (`/usr` but not `/etc`, `/var`) via libostree
|
|
- Client-side package layering (and overrides)
|
|
- Easily make your own: `rpm-ostree compose tree`

Projects using rpm-ostree
|
|
--------------------------
|
|
|
|
[Project Atomic](http://www.projectatomic.io/) is an umbrella project for
|
|
delivering upstream container technologies and combined with a minimized,
|
|
atomically upgradable host system to Fedora, Red Hat Enterprise Linux, and CentOS.
|
|
|
|
rpm-ostree is the underlying technology for host updates. The headlining project
|
|
is "Atomic Host", which is a server variant oriented towards running Linux
|
|
containers using e.g. Kubernetes. However, there is now also a Workstation
|
|
variant, showing the full generality of the rpm-ostree model.
