Re: [gentoo-user] Remove redundant entries in world - howto
The following lines creates an auditWorldFile.log log file which will
show packages requires by other packages, so theones you can safely
remove.
#!/bin/bash
n=`wc -l /var/lib/portage/world|awk '{ print $1 }'`;
for i in `seq 1 $n`;do
pkg=`cat /var/lib/portage/world|head -n$i|tail -n1`;

echo -e /tmp/auditWorldFile.log
done;

If it wouldn't be removed it's obsolete in world.
Unfortunately this has to be done in several rounds.

Hi,
I wanted to add, that a minimal world in my opinion isn't always what you
want. For example in the time I searched for a suitable window manager for
me I did a lot of depclean these days and accidently removed the xserver.
There was no harm done, but I figured, that my world file should contain all
packages, that should never removed automatically unless I want to. This way
there is a little less danger involved using depclean. So this type of work
might only be done by hand.

[gentoo-user] Remove redundant entries in world - howto
Hi, does anybody know about an easy method to remove all entries from /var/lib/portage/world which would have been pulled in anyway even if they were not contained in world. My current attempt would be to write a script which executes emerge -vpc on each entry in world. If it wouldn't be removed it's obsolete in world. Unfortunately this has to be done in several rounds. Many thanks for a hint, Helmut.

That command switch is the functional opposite of --noreplace. I think you will find a wealth of information in the manpage for emerge. Happy reading! -- Matthew W. Summers

Many thanks for a hint, Helmut. In my experience the world file isn't huge - 50-100 lines - but only if it contains the things that really need to be there. I've simply commented out specific entries and run emerge -pvDuN @world to determine if the entry wasn't necessary, and if it wasn't then removed it. When I've boiled it down to things that need to be there (I.e. - I can still run emerge -pvDuN @world and there would be no changes) then I run emerge - p --depclean to look at what can be removed, make sure it's OK, and then run depclean for real. Hope this helps, Mark

The main question is which packages might be removed from 'world'? Your tools for this are two eyeballs and a brain. World gets bloated when users emerge libs and apps blindly that are covered by other packages and - meta ebuilds (avoid this with emerge -1) Edit the world file and remove everything you think might not be needed. Leave only apps you know for sure you need and want. Then run emerge -p --depclean which may or may not want to remove stuff. Inspect the list and add important stuff back into world with emerge -n. Repeat until --depclean returns null output. eix-test-obsolete also gives useful clues about redundant world entries, but not in a clearly laid out section like you are after. I know of no app that does that. -- alan dot mckinnon at gmail dot com

My current attempt would be to write a script which executes emerge -vpc on each entry in world. If it wouldn't be removed it's obsolete in world. Unfortunately this has to be done in several rounds. As far as I know there is currently no tool available for something like this. I have a skript which runs emerge -pv --depclean for every entry in world. If depclean returns reverse dependencies the package in question is redundant in world. It takes quite some time but works reliable. There are false positives for packages with PDEPENDS, but you will recognize this when emerge -pv --depclean wants to remove packages which you want to keep afterwards and you can add them back manually. Another method would be removing the world file (backup before) and run the regenworld script afterwards. The result is not really minimal so there will still be redundant entries. I asked the portage maintainer about such a tool, as it would be best if it uses the portage API to speed things up. He didn't not see the point of such a script but thought about writing something which creates a minimal word file. If you want such a functionality I recommend to open a bug about it. -- Daniel Pielmeier
