-Linux Distribution for Nodes
-============================
-
-Fuel allows you to deploy either the CentOS or Ubuntu
-Linux distribution as the Host O/S on the nodes.
-All nodes in the environment must run the same Linux distribution.
-Often, the choice is made based on personal preference;
-many administrative tasks on the nodes
-must be performed at shell level
-and many people choose the distribution
-with which they are most comfortable.
-
-Some specific considerations:
-
-- Each distribution has some hardware support issues.
-  See :ref:`release-notes` for details about known issues.
-- In particular, the CentOS version used for OpenStack
-  does not include native support for VLANs
-  while the Ubuntu version does.
-- CentOS supports .rpm packages; Ubuntu supports .deb packages.
