Disable the re-installation on reboot

[root@head ~]# wwsh provision set node0[1-4] --bootlocal=EXIT 
Are you sure you want to make the following changes to 4 node(s):

     SET: BOOTLOCAL            = EXIT

Yes/No> yes

Renaming a node interface

If we want to change the interface of node01 FROM eth0 TO eth1:

Are you sure you want to make the following 1 change(s) to 1 node(s):

     SET: eth0.NAME            = eth1

Yes/No [no]> Yes
