Located at SELF offset 0x78.

For some reason it was named vendor_id there.

In geohot's makeself it was used as: set_u32(&(output_self_info_header.i_magic), 0x01000002);.

Not directly related to Authority ID, but seems to have many simularities with it (vendorid=2nd-9th bytes of authid), seems also related to SM ; LPAR's and their order suggests hierarchy/permission from high (can do everything) to low (lesser abilities).

VendorID count filetype
