Repartitioning of HD

[Matthias Grimm <matthiasgrimm@users.sourceforge.net>]

Hi,
I have three main partitions on my Powerbook's HD: Linux (ext3), MacOS9 (HFS) 
and Swap. I would like to make the MacOS9 partition much smaller, increase 
the size of my swap partition and create a new additional Linux partition.

Is it possible to delete the HFS partition and create two new partitions (one 
Linux, one HFS) instead without destroying the existing Linux partition?

I read a lot about that and according the usual opinion HFS partitions should 
be created with the MacOS tool, but this tool don't seem to allow partition 
changing, do it? Is there a safe way to reorganise my HD without building it 
up again from scratch? The more I read the more unsure I became.

  Best Regards
