 The following assumes host systems with enabled SecureBoot (User Mode) and default platform certificates.
 If you are using custom keys, you have to sign the corresponding components accordingly.

 Every subdirectory must contain `shimx64.efi` and `grubx64.efi` file with permission mask `u=r,g=r,o=r`.
 
+There might be multiple shim binaries inside a package.
+To find the correct one you can check for the signer's common name "Microsoft Windows UEFI Driver Publisher" with the following command (Rocky Linux):
