package-management: rpm-ostree/atomic

Browse source 
Currently Atomic Host uses rpm-ostree/atomic.  There's also going
to be an Atomic Workstation, so let's mention the existence of these
tools.  For now I'm just linking to the upstream documentation.

= Package Management
All software on a {MAJOROS} system is divided into RPM packages, which can be installed, upgraded, or removed. This part describes how to manage packages on {MAJOROS} using [application]*DNF*.
There are two types of {MAJOROS} system; "traditional", which use DNF, and "image-based" which use rpm-ostree.
= Traditional package management
On a traditional {MAJOROS} system, software is divided into RPM packages, which
can be managed via [application]*DNF*.
= Hybrid image/package management
The "Atomic" variant of {MAJOROS} uses [application]*rpm-ostree* to update the
host. `rpm-ostree` is a hybrid image/package system. By default, installations
are in "image" mode using OSTree, but additional packages can be installed. It
also supports overrides, rebases, and many other features. For more information,
see link:++http://www.projectatomic.io/docs/os-updates/++[its online documentation].
Additionally, the `atomic` CLI supports installation of system containers, which
are Docker/OCI images distinct from the host user space. For more information,
see link:++http://www.projectatomic.io/docs/usr-bin-atomic/++[its online documentation].

= rpm-ostree
[application]*rpm-ostree* is a hybrid image/package system for {OSORG}. One of
the most important things to understand is that available RPMs come from the same
`/etc/yum.repos.d` sources.
For more information, see the [upstream documentation](https://rpm-ostree.readthedocs.io/en/latest/).
