// These GUIDs allow to retrieve parsed finderInfo fields out of HFSPlusVolumeHeader
// via HFSPlus.efi driver. The fields are reads from the following structure in Big Endian:
//
// struct HFSPlusVolumeFinderInfo {
//   uint32_t blessedSystemFolderID; // for OpenFirmware systems
//   uint32_t blessedSystemFileID;   // for EFI systems
//   uint32_t openWindowFolderID;    // deprecated, first link in linked list of folders to open at mount
//   uint32_t blessedAlternateOSID;  // currently used for FV2 recovery, inaccessible from UEFI
//   uint32_t unused;                // formerly PowerTalk Inbox
//   uint32_t blessedOSXFolderID;    // currently used for normal recovery
//   uint64_t volumeID;
// };
