I don't understand your motivation for using --selective=n with that |
| 38 |
command. Isn't the command useful without it? |

No, don't use --selective=n. I only mentioned it in order to explain the |

behavior that you observed. |

It's safe, but you may need --changed-deps in order for your dependency |
| 49 |
calculations to work (depends on how the dependencies of your installed |
| 50 |
packages have changed). |
