  "message": "[efi] Provide read-only access to EFI variables via settings mechanism\n\nEFI variables do not map neatly to the iPXE settings mechanism, since\nthe EFI variable identifier includes a namespace GUID that cannot\ncleanly be supplied as part of a setting name.  Creating a new EFI\nvariable requires the variable\u0027s attributes to be specified, which\ndoes not fit within iPXE\u0027s settings concept.\n\nHowever, EFI variable names are generally unique even without the\nnamespace GUID, and EFI does provide a mechanism to iterate over all\nexistent variables.  We can therefore provide read-only access to EFI\nvariables by comparing only the names and ignoring the namespace\nGUIDs.\n\nProvide an \"efi\" settings block that implements this mechanism using a\nsyntax such as:\n\n  echo Platform language is ${efi/PlatformLang:string}\n\n  show efi/SecureBoot:int8\n\nSettings are returned as raw binary values by default since an EFI\nvariable may contain boolean flags, integer values, ASCII strings,\nUCS-2 strings, EFI device paths, X.509 certificates, or any other\narbitrary blob of data.\n\nSigned-off-by: Michael Brown \u003cmcb30@ipxe.org\u003e\n",
