The way I've done it is to edit the world file, removing anything that I don't run, then do an emerge depclean -p. anything that shows up that I want to keep, I put back with emerge -n packagename. Then run depclean -p again until I am happy with what it wants to remove. There's no point in removing and reinstalling packages, especially if you are going to to emerge -e world later. -- Neil Bothwick IBM: Inferior But Marketable. signature.asc Description: PGP signature

I've been running the same gentoo system on my computer for several years now... keeping it relativey updated, but over time there's always cruft that builds up, stuff that gets left behind during upgrades, or re-installs. Packages that don't change version for a long time, and don't get recompiled with the latest compiler, etc etc and so on and so forth. So what I want to do is give my computer a complete clean-out. What I really CAN'T be bothered doing is a complete format and re-install! One idea I've had is to delete almost every entry in my 'world' file, and then do an 'emerge depclean'. That would be pretty cool, empty out a huge amount of stuff, and then start re-installing at my leisure. But what that *wouldn't* do is delete all the files in random places that aren't owned by any particular package. This would be a good thing to do when spring cleaning, as it were. Is there a tool that will allow me to find *all* files that aren't owned by any package, so that I can then decide what to do with them? Obviously skipping directories such as /home/. Then I can delete everything that doesn't look critical, hopefully without losing my stuff in places like /boot or /etc either :-) Then I think I would do an emerge -e system, and then start re-adding applications I wanted. What do you think? Does anyone have any ideas about good ways of 'refreshing' my gentoo system? All suggestions appreciated :-) Thanks! Well, what I would do is: % etc-update (to make sure that there aren't any cruft files lying around) and then: % emerge -eD world to rebuild the entire system. You could also do: emerge --newuse -D world to just upgrade things that haven't been built since you change USE options. or if you have gentoolkit installed, revdep-rebuild to verify that all packages have all the correct dependancies.

It should be fairly simple to generate such a list. You can generate
a list of all regular files that are owned by an installed package
with something like:
cd /var/db/pkg; find . -name CONTENTS -exec cat {} \; | grep ^obj |
awk '{print $2}' | sort
And then a list of all regular files on your system with:
find / -type f | grep -v -e ^/home -e ^/tmp -e ^/var/db -e
^/var/tmp | sort
Then you just have to diff the two lists to find things that are not
owned by a package...
