[Users] How to pxeboot ovrit node into memory automatically?

[David Li]

Hi Fabian,

I think the bad route is a link local route 169.254.0.0/16. I am not quite sure if it's a real bug but in my case I have to remove this route.
Also I am using ramdisk based node without a local disk. Can anything be persisted? 

David
