# Check if secure boot is being enforced.

# Per Peter Jones, we need check efivar SecureBoot-$(the UUID) and
# SetupMode-$(the UUID), they are both 5 bytes binary data. The first four
# bytes are the attributes associated with the variable and can safely be
# ignored, the last bytes are one-byte true-or-false variables. If SecureBoot
# is 1 and SetupMode is 0, then secure boot is being enforced.
#
# SecureBoot-UUID won't always be set when securelevel is 1. For legacy-mode
# and uefi-without-seucre-enabled system, we can manually enable secure mode
# by writing "1" to securelevel. So check both efi var and secure mode is a 
# more sane way.
