Colin Walters 16be1a0bad rust: Rework treefile to be an object 
In a later patch I'm going to add more API; basically rather
than doing the JSON parsing from C, we can add APIs to directly
access the treefile object.  This also demonstrates how we
can do more extensive APIs, in particular implement an "object"
in Rust.

The ownership across the FFI boundary becomes nicer here too,
we don't need to do a dance with the fd.

For writing this I found
http://jakegoulding.com/rust-ffi-omnibus/objects/
quite useful, as well as
https://github.com/rust-lang/regex/blob/master/regex-capi/src/rure.rs

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.

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 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.
