Hi,

Actually, I think the correct handling is to first bless a boot
directory (storing the directory id in header), then bless a boot file
(add +tbxi attribute), that's why the bless command in OSX needs needs
both --folder and --file option.

Yeah, osx support fat binaries that contains code from multiple architecture.
