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

emerge @system, but

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

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