To clarify a minor point here, are the amd64 disc1.iso images or
both the amd64 and i386 disk1.iso images being built as "hybrid"?

As this is what I see on my system:
root_at_x230a:/home/ISO/x # file FreeBSD-11.2-BETA2-*
FreeBSD-11.2-BETA2-amd64-disc1.iso: DOS/MBR boot sector; partition 1 : ID=0xee, start-CHS (0x0,0,2), end-CHS (0x3ff,255,63), startsector 1, 1472695 sectors
FreeBSD-11.2-BETA2-i386-disc1.iso:  ISO 9660 CD-ROM filesystem data '11_2_BETA2_I386_CD' (bootable)
