+ <title>Atomic Upgrade and Rollback via RPM-OSTree</title>
+ <para>
+ Fedora 22 includes <application>RPM-OSTree</application>, a
mechanism used on Fedora Atomic installations to perform atomic upgrades and rollbacks for
the entire system (kernel as well as userspace).
+ </para>
+ <para>
+ Instead of performing a package-by-package installation and upgrade on each client
machine, the tooling supports composing" sets of packages on a server side. Clients
can then perform atomic upgrades as a tree.
+ </para>
+ <para>
+ On systems using <application>RPM-OSTree</application>, standard package
managers (<application>DNF</application> and
<application>Yum</application>) do not work normally; they can only be used in
read-only mode.
+ </para>
+ <important>
+ <para>
+ The version of <application>RPM-OSTree</application> available in the
default <systemitem>updates</systemitem> repository and on installation media
will not work due to a known issue. To use this tool, enable the
<systemitem>updates-testing</systemitem>
<application>DNF</application> repository and update the
<package>rpm-ostree</package> package.
