emerge -uD world should want to upgrade gdm. Here's how it works: You type emerge foo, and bar gets installed as a dep of foo, and baz gets installed as a dep of bar. foo gets recorded in your world file, but bar and baz don't. All 3 get entries in /var/db/pkg. Now, if you do emerge -u world should pickup updates for foo and bar, but not baz. emerge -uD world should pickup updates for foo, bar and baz. But if foo gets removed or stops depending on bar and nothing else depends on bar, then even emerge -uD world or emerge -e world won't pickup updates of bar or baz. If you still wanted bar in this case you could do emerge -n bar, and it'd get added to your world file without being re-emerged. Why not add everything to your world file? I believe that it slows portage down because it has to check the deps of more packages. It also means that if libbar gets installed as a dep of appfoo, and then you decided you don't want appfoo anymore and unmerge it then you'd still keep getting updates for libfoo, and emerge depclean wouldn't remove it. It's also harder to maintain/find stuff in a larger world file. hth, Dave -- djm -- gentoo-user@gentoo.org mailing list
