And not enough is there to really be effective in using the 
technology.  Just the basics.

And how do you set other types? I could boot with a ghost 9 rescue CD 
(which I did not bring with me) and edit the partition table.  But is 
there a Linux tool to do this?

oh, so a0 is a partition type.  What IS the partition type that Linux 
makes for its boot, swap, and EXT3 filesystems?  How do I see this 
without something like Ghost recovery?

I have seen this, and it looks like I will have to use LVM:


So I would have to put / and /home into the LVM partition...

Well the kickstart command is part:

part /boot --fstype ext3 --size 100
part / --fstype ext3 --size 10240 --grow
part /home --fstype ext3 --size 25600
part swap --size 2048

if [ $numhd == "2" ] ; then

Does not look any different in terms of part commands than you can 
put into kickstart.  Just the logic to take advantage of it all.
I **AM** reading as much as I can find, but I am not finding enough 
of what I need....
