I think we have issues with librepo not handling being forcibly interrupted; I saw an lzma error from what I think was a partial download. Let's add an error prefix here so this is easier to debug. I think we used to have a prefix but lot it when we moved to async. Closes: #1477 Approved by: jlebon
rpm-ostree: A true hybrid image/package system
rpm-ostree combines libostree (an image system), with libdnf (a package system), bringing many of the benefits of both together.
+-----------------------------------------+

| | 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) |

Features:
- Transactional, background image-based (versioned/checksummed) upgrades
- OS rollback without affecting user data (
/usrbut not/etc,/var) via libostree - Client-side package layering (and overrides)
- Easily make your own:

Projects using rpm-ostree
Project Atomic 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.
