Example for ostree update

gistfile1.txt

As an example, let's say that we have a Fedora Atomic host which is on the default ref.  That ostree will now be updated every two weeks, and only every two weeks:

```
-bash-4.3# date
Fri Feb 10 21:05:27 UTC 2017

-bash-4.3# rpm-ostree status
State: idle

       Version: 25.48 (2017-02-01 20:49:44)
        Commit: 44599db3ddf43fdefb5407d217fb575851134c7618d1a98960b25e0aabe2b8f4
        OSName: fedora-atomic
        
-bash-4.3# rpm-ostree upgrade

```

If you want the daily ostree update instead, as you previously had, you need to switch to the _updates_ ref:

```
-bash-4.3# rpm-ostree rebase --reboot fedora-atomic/25/x86_64/updates/docker-host

761 metadata, 3091 content objects fetched; 201487 KiB transferred in 73 seconds
