EFI Boot Stub on Removable Media

[Shea Levy]

Hello,

I am currently working on making the live CDs for the NixOS distribution 
EFI-bootable with the EFI boot stub as the bootloader. Is there a 
recommended way to use a boot-stub enabled kernel on a removable device 
(where, AFAIK, there is no way to tell the firmware what params to boot 
with automatically)? Currently, I'm hacking together a really 
quick-and-dirty UEFI application that reads a parameters file at a 
pre-defined location and loads the kernel with those parameters, but I'd 
love a better alternative. Is it possible to embed an initrd in a 
bzImage after the image is built? Or is there some way to have a CD tell 
the firmware what arguments to pass to \EFI\BOOT\BOOT{ARCH}.EFI? Or some 
easy tweak to the kernel source to have it use a set of default 
parameters in absence of explicitly passed ones?

Cheers,
Shea Levy
