That description is broad, it sounds like you didn't pass -uD to emerge; |
| 17 |
if it is part of the dependency graph (it should, otherwise this |
| 18 |
discussion would be useless) and is an update (it is, due to eix-diff), |
| 19 |
then with -uD it would pull that in. |

This even doesn't have to do anything with sub-slot dependencies as far |
| 22 |
as I know; because why would it check the sub-slot dependencies if it |
| 23 |
were an upgrade, the upgrade takes precedence over the sub-slot |
| 24 |
dependencies. The other option is that I am confused about this; as you |
| 25 |
can see, given the possible scenarios that could happen I might have a |
| 26 |
different one on mind than you do. |

If backtracking doesn't get to it, it would have to list it as a |
| 29 |
conflict; if it doesn't do that at the moment, then we certainly have a |
| 30 |
bug somewhere I think. Thank you in advance for investigating this. |
