If I'm getting this right the proposed behavior is such that in case of |
| 21 |
conflicting use flags emerge fails and user gets a message that he |
| 22 |
has to set use flags as required. If so then I think it is not the right |
| 23 |
way to handle it. A package manager should be able do deal with (use |
| 24 |
flag) dependencies automatically. Similarly as it deals with "normal" |
| 25 |
package dependenicies. |
| 26 |
|
| 27 |
It should not do this silenly though. emerge -pv should display real |
| 28 |
state of use flags; so if some use flag has to be turned on |
| 29 |
automatically due to dependency/conflict then it has to be shown so. |
| 30 |
|
| 31 |
This apply also for package[use_flag] deps. It is not very convenient |
| 32 |
to fiddle use flags for individual packages that I basically do not care |
| 33 |
about because they are just dependencies; so natural expectation is |
| 34 |
that package manager pulls required deps. automatically (whether it |
| 35 |
means install a package or install a package _with_ switched use flag). |
| 36 |
|
| 37 |
I hope this does not sound that I'm dictating you what is the right way |
| 38 |
to do things. I just wanted to express my opinion. And I admit that |
| 39 |
perhaps I do not see possible negative consequences of such behaviour. |
