== Para usar el servidor de nfs  ==
 * /compartir : el share_root
 * shares : directorios dentro de share_root (/compartir)
 * volgroup : device a mountar (lvm, raid, ...)
 * share_access = IP o hostname
 * share_options = rw,sync 

== ejemplo 1 ==
   include nfs_server
   nfs_share { "/compartir": 
       shares => [ "foo", "bar", "aaaa" ],
       volgroup => "",
       share_access => "192.178.0.1",
       share_options => "rw,sync,no_subtree_check"	    
    }

== ejemplo 2 ==
    include nfs_server
    nfs_share { "/home":
        shares => [ "" ],
        volgroup => "",
        share_access => "*.nuestrolan.cta.org.ar",
        share_options => "rw,sync,no_subtree_check"
