[Cooker] How to dump current rpm db for install ?

[Frank Griffin]

The current install gives you a way to save your package selections to a 
floppy which can then be used in later installs to avoid having to 
manually re-select everything.

Is there any way to generate such a floppy from a running system ?  In 
other words, once I get a particular cooker "stocked" with various 
packages added over time (many post-install), can I create a floppy that 
can be fed to another install which will select all of the packages in 
the first system, whether they were selected during installation or 
after installation ?
