I've always had to make a perl one liner to get this done and i'm surprised this feature doesn't already exist. Basically I want to be able to emerge -U world, or -u, whatever... and provide a --not-including list of packages I specifically don't want it to emerge. current ways of doing this are to write a perl script and to mask the package, this is ridiculous. We need this right away =P Reproducible: Always Steps to Reproduce: 1. emerge -U world 2. see all the packages that want to be upgraded 3. realize that you have to upgrade all of them and can't pick and choose unless you manually write emerge <package> <nextpackage> <nextpackage> 4. or you write a perl script to do it for you :\
