Hi,

I use following approach:
emerge --sync
emerge -DuavN world
dispatch-conf
emerge --depclean -pv
revdep-rebuild
glsa-check -t all

Whenever there is something changed on the way, I will start with the
world command again. Sometimes depclean will remove something world will
emerge again. I want to be on the save side for those cases.

Anyway I also seem to have orphan packages not found by depclean but not
updated by emerge -DuavN world

My Post (german):

I would be interested to hear about your outcomes to compare the
(update)result from you when comparing:
emerge -DuavN world
emerge -aev world
emerge -DuavN --with-bdeps y world

To see if some package is needed by anything you might run equery
depends <whatever package>
