Thanks; I appreciate it.

I don't think so. My Mac OS X partition, for instance, doesn't have the
boot flag set, yet it boots. In the absence of yaboot, I would imagine
it boots by means of the proper boot-device setting in OpenFirmware
NVRAM. I think it's adequate for only the yaboot partition to have the
boot flag. That said, I would definitely not want to remove the boot
flag on partitions that already have it set before partman starts.
parted looks at the state of the boot flag when deciding whether to
create an Apple_Bootstrap partition, and yabootconfig/yaboot-installer
look for such a partition when figuring out where to install the boot
loader. They then call mkofboot, which sets the boot-device variable in
NVRAM so that OpenFirmware knows where to look at the next boot.
