I think this mainly happens for very old packages not built in a long |
| 38 |
time. The install database simply misses the relevant info. Rebuilding |
| 39 |
the package should catch up on this. |
| 40 |
|
| 41 |
I usually see this on old packages installed but not updated for a long |
| 42 |
time. "emerge @preserved-rebuild" usually doesn't see them, |
| 43 |
revdep-rebuild most of the time sees them but may miss packages which |
| 44 |
@preserved-rebuild sees (because revdep-rebuild does only detect |
| 45 |
missing binary deps but cannot identify orphaned libs which are still |
| 46 |
there but should be removed). And some simply need to rebuild once to |
| 47 |
migrate to new installation meta data. |
| 48 |
|
| 49 |
Packages caught in such a way are from then on usually seen by |
| 50 |
@preserved-rebuild. |
| 51 |
|
| 52 |
I'm using only "emerge @preserved-rebuild" in a long time now, without |
| 53 |
falling back to revdep-rebuild. The latter is quite obsolete to me. |
