yaboot upgrade requirements for powerpc liveusb build

[joejoe99@softhome.net]

yaboot/powerpc bail/breaks on build w/ this command: 

lh_config -b usb-hdd 

and makes a request for a yaboot upgrade on g3 pismo/powermac and g4 emac. 

is there a place i can find an issue queue or todo for advancing this port? 

thanks very much
