Nope. It's still floating around... |

Brian Harring suggested that such an ebuild could have RESTRICT="metaebuild" |
| 44 |
which would signify that just its *DEPENDs should be processed. This would |
| 45 |
easily allow solutions to both of the above problems. |
| 46 |
|
| 47 |
The only other issue I can think of is blocking against virtuals. For example, |
| 48 |
xfree contains DEPEND="!virtual/x11". This could be handled by portage as a |
| 49 |
special case for RESTRICT="metaebuild" but that would then be one point where |
| 50 |
this whole scheme is not compatible with 2.0.50 (and Nick hates special |
| 51 |
cases ;). The only other option would be for virtual/x11 to have: |
| 52 |
|
| 53 |
DEPEND="|| ( ( x11-base/xfree !x11-base/xorg-x11 ) |
| 54 |
( x11-base/xorg-x11 !x11-base/xfree ) )" |
| 55 |
|
| 56 |
However, this could get real messy real quick - but does allow for much more |
| 57 |
expression. Thoughts on this? |
