But maybe you want to create a VIVID.tar.xz and put this into your config space.
I am guessing I can do both, right? It will use the vivid.tar.gz if it finds it.
I figured creating the basetar.gz file was optional since the basefiles subdir wasn't in my old fai config space. I guessed it was something new and probably I could figure it out later. But it was easy enough for me to create the vivid.tar.gz because my fai server is an ubuntu vivid machine.
It seems to have worked.
