9 Anything. You are rememrging packages that may have changed, or their
10 dependencies, so you are bound to find the odd problem.

22 How do you know which packages are important? By doing a partial update
23 you risk more problems and time wastage than just re-emerging @world in
24 one go.

31 No, just do it. Add --keep-going to the emerge command and it will spit
32 out a list of any failed packages at the end. Then you can deal with
33 those as and when you see fit. In the time you have spent worrying about
34 this, I have updated two systems, one after the other I wasn't brave
35 enough to try in parallel, and dealt with the build failures. You are
36 just creating more work for yourself.
