There is a file that contains all the packages you have installed. It is located here: /var/lib/portage/world One could copy that file to another system and do a emerge @world to install the same list of packages. Depending on what all you have installed, it could confuse emerge and not be doable. In the past, I had a copy of the file and I emerged them a few at a time. It's worth trying by just coping the file tho. It just might work. Since you mention being new to Gentoo, don't forget the --oneshot or -1 option when emerging things that should not be in the world file. Libraries are one thing that should rarely if ever be in that file. Once you get your install done and rarely install new packages, you can add that to the defaults in make.conf. When I first started using Gentoo, I was bad to forget the -1 option and my world file was a mess. It can lead to all sorts of problems later on. The only entries in the world file should be packages you install and use directly. It's rare that anything else should be there. Happy Gentooing. Dale :-) :-)
