How to save the list of installed packages?

I installed SUSE 10.1 on a notebook (which does not have a floppy disk drive). Now I would like to save my system configuration and the list of packages I selected during the installation on a USB key (just in case I have to reinstall everything for any reason). During the installation process, I could find no indication about the possibility to make a backup of the list of packages I just selected. Can I do it now, once the system is up and running? How?
