It's a typo and you are saying it _is_ fundamentally wrong, aren't you? If you are prepared to pick up new files, you need to crawl everywhere anyway, so if the xattr is used to leave a mark "The last time I looked at this file was this" in the file itself, it does not sound too bad to me. It would be irritating that it touches ctime, though, but I do not use it so it is not my problem ;-) http://beagle-project.org/FAQ "Do I really need extended attributes?" talks about BEAGLE_DISABLE_XATTR environment variable and interestingly it says disabling use of xattr would slow you down. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
