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

[David Li]

Hi Fabian,

Yes rootpwd worked too! Thanks.

Two new problems:

But I found there is no networking for the stateless node.
What kernel boot options are used to either use DHCP  or statically configure the IP address for an interface on the node?

I also need to have the sshd enabled. Is there a kernel option for that?


David
