I understand, but I don't have time to fix it, either. And I will never have it unless I change a job - which I have already tried and failed. But OK - I realize that I have already spent too much time trying to take it down. > That said, I don't mind a warning message or two when trying to load a > module that has known crashers, and that we don't have time/energy to > fix.

IMHO the messages in the module and in the configure script have different target audiences. The message in the module is indeed targeted at users and should indeed be reworded to be more to the point to inform them that there are known bugs. The message in the configure script is not targeted at users, it targets distributors, and thus needs a different wording than a message to users. > > As for building by default, I don't have a strong opinion on whether we > do that or not - distros will disable or re-enable as they see fit anyhow. > -- Alexander E.
