Dear Guys,
I am using cobbler with oneSIS. Reason for using oneSIS is, i am
trying to push the golden image created on cobbler server. Since cobbler
supports installation only from iso's, i had to use both together.
I read the documents on pxe_just_once option, which says enabling
it would eliminate boot loop problem. So i set it to 1, and started
transferring images.
The approach to install OS on remote node is first install it in
diskless mode followed by script, which makes it disk-based.
Now my question is, would the kickstart file be called ever as its
being booted in disk-less mode followed by disk-based?
What should be the correct approach to achieve the same?
cobbler system getks --name=n3 has the following output
