Ideally, this would be handled entirely by EAPI 5 slot-operator |
| 22 |
dependencies. However, it seems like we'll need some form of sub-slot |
| 23 |
pass-through [1] and/or sub-slot dictionaries [2] before we'll be able |
| 24 |
to achieve complete adoption of slot-operators. |

Meanwhile, adding a preinst sanity check seems like a good idea. The |
| 27 |
LinkageMap class that's used for preserve-libs already has all of the |
| 28 |
info that we need about installed libraries, so it's just a matter of |
| 29 |
checking the binary package's NEEDED.ELF.2 entries against that. |
