I am not aware of yaboot using any non-standard DHCP options. Or did you maybe mean pxelinux options instead? pxelinux is also a secondary stage boot loader, but for x86 instead of PowerPC machines. pxelinux seems to highjack some DHCP options (see RFC 5071). Looking at those options, it seems to me that these are all configuration options for the bootloader... that highlights one of the main problems with DHCPv4 network booting again: There was no official way to pass parameters to the bootloader or OS kernel that was loaded by the firmware. So I think that such an option highjacking won't happen with DHCPv6 again: Since we've got a "parameter option" in our draft already which can be used to pass such configuration data to the bootloader/kernel, there is no more need that they abuse extra DHCP options for this.
