It wouldn't, it, if it really were "secure", would not allow any command line parameters to be changed. Which is exactly what those bootloaders who "claim" to be secure do. And, just to butt in here, there is no requirement that I have ever heard of from anyone at UEFI or Microsoft that this type of "kernel feature" is a requirement to allow for a bootloader/kernel to be signed with their key. So that should take the "politics" reason off the table here, if people thought that somehow it was even a viable reason... thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
