I agree that it feels a bit wrong to sound as if we are blaming the messanger (the one that notices a possible misconfiguration), but you are correct that we should make a note on why we think it is a good idea to add this piece of extra documentation in the history.

Perhaps. Right now, the only case people noticed was that we complain when the effective user cannot even tell if config file(s) exists or not. Labelling this option as "Treat unreable as missing" is fine, but "an inaccessible homedir is OK" is vastly different. Imagine a new version where we start _requiring_ something to exist (and we read from it) and imagine further that the expected place of that thing is somewhere inside $HOME. We cannot keep the promise to those who set "an inaccessible homedir is OK" option when that happens, as we may need that piece of information we wanted to read from there in order to properly operate. In any case, I think the loosening is an independent issue. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
