So basically you want a CD that fires up pxelinux.0 to a next-server
address that does not originate from DHCP.
That, or I'd be happy with a small kernel/initrd that could do it.
Not sure you can do this without hacking up pxelinux source.
No, I didn't think so :(
(The Live CD is not any more overkill than what you propose above,
and
does so without needing TFTP. Again though, we're not finished
resurrecting it.)
Thanks - I think I'm stuck with either:
a) cobbler buildiso per system
b) cobbler buildiso
(since both need a menu selection anyway, I'm no worse off really).
Or of course
c) bribe the DHCP admin with beer and pizza.
