Rebuild
========

You can rebuild your slice at any time, replacing it with a fresh install of the Distribution OS image 
of your choice.  Any assigned :doc:`IP Addresses <addresses>` and :doc:`firewalls <../networking/firewalls>`
*will not* change.

.. Warning::

   Rebuilding a slice will **destroy all data** on that slice, replacing it with a fresh OS install 
   of the distribution of your choice.

To rebuild a slice:

#. Select the OS image of your choice in the selection box.
#. Enter a password for the rebuilt slice.

Click the :guilabel:`Rebuild` button to proceed to the build screen.  The process is similar to 
creates, except the slice name, IP addresses, and firewalls (if any) are retained.

.. Note::

   After a rebuild, SSH will give the notorious "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!" 
   upon trying to login again for the first time.  This is correct and to be expected, because the 
   host key *has indeed changed* due to the OS reinstall.

.. Tip::

    Slice rebuilds are a great tool for "test driving" other distributions.  Also useful for speeding
    up testing and/or debugging deployments of your own software on different distributions.
