boot loader to chain-load signed boot loaders (signed by Debian)

This package provides a minimalist boot loader which allows verifying signatures of other UEFI binaries against either the Secure Boot DB/DBX or against a built-in signature database. Its purpose is to allow a small, infrequently-changing binary to be signed by the UEFI CA, while allowing an OS distributor to revision their main bootloader independently of the CA.

This package contains the MOK manager and fall-back manager signed by the Debian UEFI CA to be used by shim-signed.
