Colin Walters e3be475566 compose+rust: Parse includes via Rust too
This follows up to https://github.com/projectatomic/rpm-ostree/pull/1576
AKA commit 2e567840ca - we now process
treefile inheritance in Rust code.  Previously for elements which
reference external files (`postprocess-script` and `add-files`)
we'd hardcoded things to only look in the first context dir.

Now we open file descriptors in the Rust side for these "externals"
as we're parsing, and load them C side.  Hence we'll correctly handle
a `postprocess-script` from an included config.

Other advantages are that the include handling was ugly un-typesafe C code
with no unit tests, now it's memory safe Rust with unit tests.

The downside here is I ended up spelling out the list of fields
again - there's probably a way to unify this via macros but
for now I think this is OK.

Closes: #1574

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.
