-- A binary representation of the UEFI variable store. Only non-volatile
-- variables are stored. This is a base64 encoded and zlib compressed
-- binary value that must be properly encoded.
--
-- When you use
-- <https://docs.aws.amazon.com/cli/latest/reference/ec2/register-image.html register-image>
-- to create an AMI, you can create an exact copy of your variable store by
-- passing the UEFI data in the @UefiData@ parameter. You can modify the
-- UEFI data by using the
-- <https://github.com/awslabs/python-uefivars python-uefivars tool> on
-- GitHub. You can use the tool to convert the UEFI data into a
-- human-readable format (JSON), which you can inspect and modify, and then
-- convert back into the binary format to use with register-image.
--
-- For more information, see
-- <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/uefi-secure-boot.html UEFI Secure Boot>
-- in the /Amazon EC2 User Guide/.
