I really get frustrated running an emerge --ask , and then coming back, finding portage has told me "hey, yep, this will work", pressing "y", and then finding "no, this won't work".

That's wasted effort.

If this default is too controversial to change, can we have an option to put in EMERGE_DEFAULT_OPTS ? I'm really tired of this behaviour.
