mac os upgrade dual boot setup

Ok I have a dual boot mac g4. i wanted to upgrade to leopard
so i noted that the hard drive partition setup is
/dev/hda1 Apple_partition_map
/dev/hda2 bootstrap yaboot
/dev/hda3 swap
/dev/hda4 Linux / 15.6G
/dev/hda5 Mac OsX 11.8G

so then i booted into new leopard installer disk, wiped out old Tiger, reinstalled from scratch to mac partition
then i did
power on
hold down apple,option, o,f buttons (yes 4 buttons)
then at > prompt type
>boot hd:2,yaboot

here 2 is /dev/hda2 ie yaboot bootstrap partion
then type

Login to linux system
run as root
fdisk -l
and look to what the macosx partition is

ON my system it changed from /dev/hda5 to /dev/hda6!!! with the new install, wasting a good 120M of space on the drive...

Then edit /etc/yaboot.conf to set
macosx=/dev/hda6 or whatever

then as root run
this will reinitialize the boot sector to boot to yaboot and
choose Linux as default or Leopard.

Then install OsiriX to MacOsX partition :)
