Here is how to get the parameters from the server to the client. All that
remains is for the code that currently for boot parameters to look here too.
If
you will direct me to that code, I will propose something.
btw - my personal goal is to be able to use this to fix a hijacked box. But it
will fit in nicely with Clonezilla: put unmodified Clonezilla CD in box, boot,
ssh in from 2nd box, run clonezilla. Which I currently can do with PXE, but it
would be nice for those that do not have that setup and just want to boot/run
from a physical CD.
