Jonathan Lebon ee458c3c50 daemon/upgrade: Write out new cached update
Right now, cached updates generated during "check" policy runs are
completely decoupled from upgrade operations. This can lead
to the surprising situation where the "Available update" is *older* than
a freshly deployed pending tree with `rpm-ostree upgrade`.

We should just generate a cached update after upgrade operations. This
is also prep for staged deployments, where we'll want to do this as
well.

Note that we write out the cached update here even if automatic updates
are turned off since it's essentially free. I've been thinking about
always displaying that information after an `rpm-ostree upgrade` in
`status`. Though not sure if we should keep it in a separate "Available
update" section, or somehow morph it as part of the pending deployment
output.

Closes: #1344

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.

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