If no cache dir is given in the workdir, we would alias the cache dir fd to the workdir fd. But of course, this meant that we'd try to close the same fd twice when freeing the compose context. Instead, let's just copy the fd as is also done in the non-unified path. Closes: #1697 Closes: #1698 Approved by: lucab |

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.
+-----------------------------------------+

| 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 (
/usr
but 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.

Talks and media
A number of Project Atomic talks are available; see for example this post which has a bigger collection that also includes talks on containers.
