The goal is to make package sets behave in a consistent way. |

As do I, which is why I haven't simply changed it. |

Well, the primary goal is to make all sets behave in a consistent way. |
| 29 |
And some sets have the explicit purpose to rebuild stuff, so making |
| 30 |
sets "selective" by default also has issues. |
| 31 |
The proposed change would also make sets behave in the same way as |
| 32 |
packages which is IMO another benefit. |
| 33 |
But as I said, I can see that it could upset people. |
| 34 |
|
| 35 |
One possible solution that I've thought about would be to remove the |
| 36 |
hardcoded "selective" parameter and let the set configuration determine |
| 37 |
if a set is selective or not (with missing = "false"), and then enable |
| 38 |
it for world and system in our default config, e.g. |
| 39 |
|
| 40 |
[world] |
| 41 |
class = portage.sets.files.WorldSet |
| 42 |
selective = True |
| 43 |
|
| 44 |
and extend the --rebuild option with new arguments "always" and "never". |
| 45 |
Don't really like the additional complexity though (and I haven't |
| 46 |
checked how much work it would be). |
