Hi! So im wondering, and i have not really done any research, if this has been up on discussion before.. but, wouldnt it be a pretty neat thing to do, to make "emerge --sync" do a diff on your /usr/portage compared to the remote repository.
Then, just merge the differences. Would obviously make alot of sense, if you do, say, daily emerge --sync's. (so you could like check if the diff became more than X lines, then just clear /usr/portage (as it does today)) Sounds like a good idea, in my head, atleast... Best regards /N
