[gentoo-user] unmerge meta packages problems

[Constantine Kardaris]

Hi,

i'd like to ask you if it's possible to unmerge the dependencies of a
meta package that installed automatic but have recorded in world file
after a while.
For example, i want to unmerge gnome-light but many dependencies have
already re-emerged without oneshot option and have recorded in world
file. So "emerge -C gnome-light || emerge --depclean" does not help anymore.

Regards,
con

You have to edit world file manually
and remove everything but the packages you really need
and then run emerge --depclean again.

yeah it seams there is no other way than manual edit world file...

You can find packages in world that are dependant upon something else
you have installed with a script like this:

for pkg in `cat /var/lib/portage/world` ; do
    count=`equery depends $pkg | grep / | wc -l`
    test "$count" -gt 0 && echo $pkg
done

You can then just remove these packages manually from world, and
depclean will work correctly if you remove any of the dependencies.
