[gentoo-user] Howto generate a list of installed packages?
Season's Greetings to one and all. I would like to be able to generate a script or list of packages of some kind that would enable me to install Gentoo with an identical profile of installed packages. Since with Debian/Ubuntu one can run dpkg --get-selections file and dpkg --set-selections file (or some such), one imagines that the Gentoo gurus/magicians are able to do something similar. It takes me months to get a new machine up to speed. In fact, I have just realized I don't have tcsh installed, something I hardly EVER use, but need to run a one of a kind script. Can anyone make a suggestion? Am I missing something? Thanks Alan Davis

Thanks Alan Davis You already have such a thing - it's the entire contents of: /etc/portage/* /etc/make.conf /etc/make.profile /var/lib/portage/world* Copy those files to a destination machine, adapt variable things like CHOST and ACCEPT_KEYWORDS to the new machine, and let portage do it's thing. If you simply want a list of packages (sans USE flags etc), emerge -e world and parse it through your favourite text pipes (grep, sed, awk, etc) then redirect somewhere If you want a list of installed packages with USE flags, emerge -e world Note that these last two just give you a (mostly) human readable list. They are not much use to portage. -- alan dot mckinnon at gmail dot com

The biggest difference being maybe some change in hardware. If you want a list of what is installed, try this: equery list That should list all packages installed but the majority of them are dependencies so you should not emerge them individually. Copying the world file I would think would be the best solution. Dale :-) :-)

Copy that file over to you new system and do a emerge --sync emerge -puDN world and you should be done. Norman

Thanks Alan Davis You might also consider a stage4 installation: http://en.gentoo-wiki.com/wiki/Custom_Stage4 I have just gone through this procedure to re-install gentoo on a laptop that had not been updated in a very long time.

Am I missing something? qlist -I (from portage-utils) or eix -I --only-names will give you a list of everything installed. Although if you straight installed everything from such a list it would probably pollute the new machines world file somewhat, but it would be a good catch anything I missed.
