There is no easy way to check what depends on any kde or gnome aplication or
library before unmerging them.. If you have eix* installed you should be able
to get something decent out of this though:
# eix -IC gnome --format '<category>/<name>' | grep -vr '^$\|^\[\|^Found' | \
while read pkg; do equery depends "$pkg"; done | grep -v ^gnome
That should show packages that are not in the gnome categories but which
depend on something from the gnome categories. Likewise for kde:
# eix -IC kde --format '<category>/<name>' | grep -vr '^$\|^\[\|^Found' | \
while read pkg; do equery depends "$pkg"; done | grep -v ^kde
-------------------------------------------------------------------------------------------------
To unmerge everything in the kde-{base,misc} categories you may do (be
careful - this does not check if anything depends on those packages):
# cd /var/db/pkg && emerge --unmerge --ask --verbose kde-{base,misc}/*
To unmerge everything in the gnome-{base,extra} categories you may do:
# cd /var/db/pkg && emerge --unmerge --ask --verbose gnome-{base,extra}/*
Both of those commands remove things without checking if any packages depend
on them.
When done removing those you should use depclean. Make sure to read the
WARNING and inspect what it will remove carefully to make sure that it does
not remove something you want to keep. This shows packages that are no longer
required by any packages in your world file.
# emerge --depclean -vp
When you are done with that it is important that you run revdep-rebuild to
repair any broken dependencies.
# revdep-rebuild -i -p -- -v
# revdep-rebuild -- -v
-------------------------------------------------------------------------------------------------
* If you do not have eix I would recommend the following. eix is really
useful:
# emerge -va eix && update-eix
