There is actually a huge functional difference between the two that you |
| 23 |
are missing here. A meta package defines its dependencies in full |
| 24 |
dependency syntax. This means you can specify versions, USE flag |
| 25 |
dependencies, make packages dependent on USE flags, etc. A package set |
| 26 |
is just a list of packages (potentially constrained by version. TTBOMK, |
| 27 |
there is no inclusion of any USE flag functionality in sets. |
| 28 |
Additionally, let's say you have a more complicated dependency like || ( |
| 29 |
A B ), I don't think there is a way to describe that in a package set |
| 30 |
at all. |
| 31 |
|
| 32 |
I'm not sure I see the merit in pushing for package sets in the bulk of |
| 33 |
cases for this reason. Maybe there is some scenario where package sets |
| 34 |
are a better option, but you haven't enumerated what that might be (and |
| 35 |
I'm not really interested in brainstorming until I come up with one, so |
| 36 |
I'll wait for one frmo someone else) |
| 37 |
|
| 38 |
Of course, my sets knowledge is a little limited compared to some |
| 39 |
people, so if something I've said about package sets is incorrect, |
| 40 |
please feel free to correct it. |
