@ -33,6 +33,15 @@ Variables you could set to customize the build:
install targets
- ENABLE_HTTPBOOT
build support for http booting
- DISABLE_EBS_PROTECTION
On systems where a second stage bootloader is not used, and the Linux
Kernel is embedded in the same EFI image as shim and booted directly
from shim, shim's ExitBootServices() hook can cause problems as the
kernel never calls the shim's verification protocol. In this case
calling the shim verification protocol is unnecessary and redundant as
shim has already verified the kernel when shim loaded the kernel as the
second stage loader. In such a case, and only in this case, you should
use DISABLE_EBS_PROTECTION=y to build.
- REQUIRE_TPM
if tpm logging or extends return an error code, treat that as a fatal error.
