Changing boot variables for LiveCD spin

[Thanster]

Hi,

I'm building a custom spin to meet an appliance requirement, I would like to edit various boot related options:

kernel command line (to revert to old style nic names)
boot timeout
etc etc.

I'm using live-cd-creator to generate my spin, but I cant work out how to edit this part of the CD/DVD as it is outside of the loopback filesystem, and is added later......

any pointers?
