That seems like a reasonable solution to me. I've been working on |
| 19 |
cleaning up the relevant code and things like that should get easier |
| 20 |
to implement as I make more progress. |

What about atoms that are greedy wrt installed SLOTs? Maybe there |
| 23 |
should be a set config option for that too. There are currently some |
| 24 |
special cases in depgraph.xcreate() and action_depclean() that |
| 25 |
implement greedy atoms for the world set. I've been pondering the |
| 26 |
idea of making world non-greedy for slots by default [1], since you |
| 27 |
can add slot atoms to the world file to pull in any specific slot(s) |
| 28 |
that you want. |
