Using same USB drive with multiple computers.

["monty19@ hotmail.com" <monty19@xxxxxxxxxxx>]

I have Fedora installed on a USB drive and use it with a laptop.  It works 
very well, but what I would like to be able to do is plug it into a desktop 
or another laptop and be able to use the same install, without having to 
completely reconfiguer the system each time I move it.  I am wondering if 
there are any programs out there to save the system configurations for 
multiple hardware configurations.  I tried doing some google searches but 
did not come up with anything, was wondering if anyone here knew about 
anything?
