You will need (at least) two partitions for YDL:
-a "swap" partition for virtal memory;
-a "root" partition for the linux filesystem
Linux cannot be installed "on top of" an HFS filesystem - it needs it's
own. However, there is an extension (MountX) that will allow you to
mount the linux ext2-formatted partition in MacOS, and you han mount HFS
(but not HFS+ to the best of my knowledge) partitions in linux.
I have an older machine that boots via BootX, but your iMac should (I
think) use yaBoot to get into linux from MacOS. Unfortunately, I am
pretty sure both of these need to read the linux kernel from your MacOS
(HFS) drive and will not work with an HFS+ drive.
You might consider a 2gb HFS partition for just the MacOS, 4gb ext2 for
YDL, 256mb for linux swap, and the balance HFS+ for all your other MacOS
stuff - with the caveat that anything on the HFS+ will be invisible to YDL.
