--- Hi, I'd like to specify a default initrd path for the EFI stub at compile time. Is there a way to do this? I got it to successfully load an initrd by setting the parameter in CONFIG_CMDLINE with this proof-of-concept patch on 3.16. (This patch is against the efi tree's next branch.) If the EFI stub doesn't currently support this functionality, I'd appreciate it if something like this could be applied. Thanks.
