Safe Re-Partitioning?

[Raymond Popowich <popowich acsu buffalo edu>]

I have had my Red Hat 5.1 system running for a while now and I have a
good idea about how much space I need allocated to my different file
systems (/home, /tmp, /var, etc)  I currently have only a / and swap
partitions.  Is there a safe way to repartition a system without
loosing any data?  I would like to break my system up into /, swap,
/tmp, and /home partitions.  I could not find any usefull information
in the man's or the online support pages.  Any thoughts would be
appreciated.
