It's safe to remove emul-linux-x86-* to see what happens next; and |
36 |
fixing it is trivial. So: |
37 |
|
38 |
- remove those packages |
39 |
- fiddle make.conf |
40 |
- emerge world using -p and inspect the list |
41 |
|
42 |
If you don;t like what you see, revert your edits and remerge |
43 |
emul-linux-x86-*. They are binary packages so the emerge is rather |
44 |
quick. As long as you didn't re-merge anything else in the interim, |
45 |
nothing will break |
