tags 572925 patch thanks linux-base package already transforms old yaboot.conf unix block device names into persistent device names on upgrades. Yaboot just got bug fix for #572869 and will be able to parse such configuration files. We should commit the attached patch and upload yaboot-installer at the same time, or soon after fixed yaboot reaches squeeze.
