And if you are a old fart who has bad memory like me, put it in the make.conf as a default. That way it takes no effort to keep a clean world file but does take effort to add something to the world file. I have to rebuild a individual package a lot more than I need to install a new package. I learned long ago, don't trust my memory to do things by default. Heck, I have to think about it to remember to add the -N to regular updates still. I been doing that for years. If it wouldn't screw up other things, I'd set it as a default but that causes another set of issues. Go ahead, tell me to do updates in script. ROFL Dale :-) :-)
