Colin Walters 95e9aa4284 Introduce `ex livefs` There are a few different use cases here. First, for layering new packages, there's no good reason for us to force a reboot. Second, we want some support for cherry-picking security updates and allowing admins to restart services. Finally, at some point we should offer support for entirely replacing the running tree if that's what the user wants. Until now we've been very conservative, but there's a spectrum here. In particular, this patch changes things so we push a rollback before we start doing anything live. I think in practice, many use cases would be totally fine with doing most changes live, and falling back to the rollback if something went wrong. This initial code drop only supports live layering of new packages. However, a lot of the base infrastructure is laid for future work. For now, this will be classified as an experimental feature, hence `ex livefs`.

rpm-ostree Overview

rpm-ostree is a hybrid image/package system. It uses OSTree as a base image format, and supports RPM on both the client and server side using libdnf.

For more information, see the online manual: Read The Docs (rpm-ostree)

Features:

Atomic upgrades and rollback for host system updates
A server side tool to consume RPMs and commit them to an OSTree repository
A system daemon to consume OSTree commits as updates

Projects using rpm-ostree

Project Atomic uses rpm-ostree to provide a minimal host for Docker formatted Linux containers. Replicating a base immutable OS, then using Docker for applications.
