For example. You emerge someprog, which has a dependency for somelib, so emerge install both packages but only adds someprog to world. Then you decide that you don't want someprog so you unmerge it, but somelib is still there, even though nothing else requires it. Normally, emerge depclean -p will show that somelib needs to be removed, but emerging updates the way you suggest could result in it being in your world file, so it will be considered as necessary to your system, even though the only function it now fulfils is taking up hard disk space (and possibly providing a security risk). > > If you want to pick individual packages from "emerge -upv world" for > > merging, merge them with the --oneshot argument to prevent them being > > added to world. > Humm....OK, or go back once in awhile and clean up your world file by > hand. Assuming you can remember which files you do and don't want, out of the hundreds of extra lines you end up with in world. Trust me, I learned this the hard way and spent some time cleaning things up. If you want to do things the hard way, that's up to you - Gentoo is about choice :) But you really shouldn't recommend this sort of bad practice to others without at least warning them first. The world file is a powerful concept in portage, if used correctly,. Filling it up with a list of all installed packages completely negates its usefulness. -- Neil Bothwick Hm..what's this red button fo|'».'NO CARRIER
