I don't like the idea to have compatibility to existing bootloaders. It sounds like a beginning of nightmare.
Not necessarily. One could do this modular, just like the sound drivers are now.. :)
Instead, Linux CDs can directly support FILO. Boot CDs can have /boot/filo.conf, and installers can generate /boot/filo.conf in the installed hard disk. It's technically easy. Stefan Reinauer was positive to add this support to SuSE's installation CD when I talked to him about this issue.
For the user interface, one could go the way with modular code, too. Elilo, the EFI boot loader, does a nice thing there. It has a "chooser" interface, allowing several user interfaces. Each user interface has a name, a probe function and a choose function. The probe function can check whether the current chooser works on the current machine (on Itanic this could be checking UGA availability before trying to show a graphical menu)
Maybe, we can make FILO to have the default config file in ROM, which includes the filo.conf from boot device (CD or HD). So the config file in ROM knows how to boot Etherboot in ROM. But this is too complicated at the moment.
How would that config file have to look? Something similar to the grub menu.lst would be fitting, wouldn't it?
