This is why adding some options to make.conf is a good idea as you already know. I added -1 ages ago. Why? I would be trying to get a update done and needed to do a few by hand and would forget the -1 option. One can only imagine what the world file looked like. lol Since I added -1 to make.conf, nothing has went into the world file that I didn't add there on purpose. Of course, one has to remember to use --select y to add those new packages but in general, I may do that a few times a year where I average updating about twice a week. Plus, when you do -a --depclean and it spits out the list, you will see it and slap your forehead and then go add it if you really want to keep it around. In all honesty, I can't imagine how a person can keep a Gentoo install up to date without adding that or having a really crappy looking world file. ;-) I wonder why the -1 isn't there by default??? I would think it would be a problem only when doing the initial install, when you want to add a lot of packages to the world file since most likely, nothing is there. Just a thought. Dale :-) :-)
