The set is created when needed, but the emerges triggered by |
| 25 |
revdep-rebuild will clear it. However, if you read the full thread, you |
| 26 |
will see the reasons why reserved-rebuild is the preferred usage. It |
| 27 |
avoids breakage and is much faster, and you can always run revdep-rebuild |
| 28 |
after to be absolutely sure. |

However, because portage keeps the old libraries around for |
| 31 |
preserved-rebuild, to avoid breakage, revdep-rebuild may fail to rebuild |
| 32 |
all necessary packages. |
