Hi all,
My question is straightforward, under what circumstances emerge world
re-emerges packages even if installed and updated?
So, strictly speaking, emerge takes an atom and will install that. In
this case, 'world' is the atom. 'emerge world' will REINSTALL every atom
in your world file (.../var/lib/portage/world). The canonical way to
UPDATE all packages is with the short options "-uDN", emerge -pvuDN
world.
To break that down further, if you were trying to install
'app-editors/vim' then 'emerge vim' would install vim the first time and
keep reinstalling vim every subsequent time, but 'emerge -u vim' would
only update vim if needed.
Hope that helps,
Jeremy
