If I have FEATURE=-preserve-libs, that's what I want. Exceptions should |
| 22 |
be limited to what will break the toolchain (including revdep-rebuild |
| 23 |
here, since that's what's normally used to get out of the situation) |
| 24 |
itself. |
| 25 |
|
| 26 |
If there was a way to handle it so a general revdep-rebuild run would |
| 27 |
still detect the preserved library as missing and do the necessary |
| 28 |
rebuilds, it'd be one thing, but if the libraries are there, it figures |
| 29 |
things are OK unless you've fed it that specific library, thereby making a |
| 30 |
general revdep-rebuld run useless at the very task it was designed to fix. |
| 31 |
|
| 32 |
Talking about which... What about creating an eutils (or whatever) |
| 33 |
function to handle the critical preservations, having it build a |
| 34 |
centralized list of them somewhere, and having a revdep-rebuild mode that |
| 35 |
will treat that list as if it had been fed in with --library on the |
| 36 |
command line? Make revdep-rebuild able to run this mode either on its |
| 37 |
own, or as part of an otherwise general run, and then you can have |
| 38 |
packages (or the package-manager itself, if it uses the list as well) |
| 39 |
preserve libs as they wish, without interfering with the ability of revdep- |
| 40 |
rebuild to detect and resolve the issues in a normal run. |
