Red Hat doesn't use all my hard drive space...

[Sean Earp <smearp mac com>]

Morning all-

I searched the archives and did not find an answer, so be gentle if it 
has been asked before.

I have a computer that I am using to learn Red Hat on.  It has two 30GB 
HD's that are completely empty.  When I go to install Red Hat 9 or 
Severn, using the default installer options, it wants to format my hard 
drives as follows:

hda:

100MB as boot partition
29.something GB as /

hdb

1GB as swap
29.something as completely empty

Is there any reason why it does not assign anything to the 29 empty 
Gigabytes on the second drive?  I can manually assign it to /home (or 
whatever), although that automatically bumps the swap partition to the 
first hard drive... Am I doomed to having to manually assign that extra 
space, or is there a reason that it doesn't use almost half the space 
available to it?  Any information would be greatly appreciated,
