And when you log in on several terminals you usually want same $PATH. You don't do that by sharing VM between shell processes, do you? Sure, that would work with sufficient kernel-side hacks for joining thread group and making e.g. bash multithreaded. Nobody does it though - it doesn't buy you anything really useful. > How can libpam join the user's existing namespace? > > Having a separate usermount-namespace for each login of the same user > would not be nice to use. I don't see why. _IF_ you can change the set of mounts after you log in, there's no more need to do any kernel tricks for that stuff than you would need for environment, etc. If you can't - well, the last point where you can get something set up is login with no changes afterwards. In that case everything is just as trivial... - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
