137There are some partitions named: <path>Apple_Driver43, Apple_Driver_ATA,
138Apple_FWDriver, Apple_Driver_IOKit, Apple_Patches</path>. If you are not
139planning to use MacOS 9 you can delete them, because MacOS X and Linux don't
140need them. To delete them, either use parted or erase the whole disk by
141initializing the partition map.

145<c>parted</c> is able to resize partitions including HFS+. Unfortunately it is
146not possible to resize HFS+ journaled filesystems, so switch off journaling in
147Mac OS X before resizing. Remeber that any resizing operation is dangerous,
148so attempt at your own risk! Be sure to always have a backup of your data
149before resizing!

468NewWorld machines can boot from any of ext2, ext3, XFS, ReiserFS or even
469HFS/HFS+ filesystems. On OldWorld machines booting with BootX, the kernel must
470be placed on an HFS partition, but this will be completed when you configure
