For updates within a Fedora release (for example, Fedora 23 Atomic Host),
you would use the `atomic host upgrade` or `atomic host deploy` to set up a
specific tree from your composed repo.  This is the standard mechanism for
updating the host OS.

For upgrading to a new Fedora release (for example, from Fedora 23 Atomic
Host to Fedora 24), the standard mechanisms don't work.  Instead you need
to add a new tree repo to sync and re-baseline.  The wiki page shows how
you would go about doing that, and that uses the `ostree` commands.  You
could replace the last `rpm-ostree` command with the `atomic host rebase`
command, if you wanted to.
