Actually, now I have a general idea of what's going on and that sounds like an |
| 35 |
acceptable solution but perhaps I could be better. This is what happens: |
| 36 |
|
| 37 |
1. revdep-rebuild uses ldd to find breakage. It finds breakage in |
| 38 |
libdbusservice.so because firefox uses tricks to preload the library from it's |
| 39 |
directory. |
| 40 |
2. revdep-rebuild find that thunderbird provides the library and thinks it |
| 41 |
needs to be rebuild. (And wrongly tells you that firefox links against it). |
| 42 |
|
| 43 |
A better way would be: |
| 44 |
|
| 45 |
1. same as step 1 above |
| 46 |
2. revdep-rebuild checks the package that provides the broken binary (in this |
| 47 |
case the firefox package), if this package also provides the missing library |
| 48 |
then it's safe to ignore the problem. |
| 49 |
3. same as step 2 above. |
| 50 |
|
| 51 |
Another solution is to make patch firefox to use RPATH so ldd can find the |
| 52 |
labraries, this would also make prelink work better with firefox but it's |
| 53 |
probably not ideal to mantain. |
