My unattended daily system maintenance procedure is like this:

layman -S
emerge --sync
emerge -pvDuN world
emerge -pv --depclean
eclean -p distfiles
eclean -p packages

And then attended like this:

emerge -DuN world
revdep-rebuild
etc-update
elogv
emerge --depclean
eclean distfiles
eclean packages

Am I missing any good stuff?
