    Nit: SELinux figures out what to label new files fine, just not based on
    the name. This works in most cases, eg., when user_t creates a file in
    /tmp it becomes user_tmp_t, incidentally this is something that AA
    cannot handle, if the filenames aren't normalized (they normally
    aren't). For example, my ssh agent socket is stored in
    /tmp/ssh-XXXXXXXX, where the X's are random characters, AA can't
    differentiate admin ssh agents from unprivileged user ssh agents,
    showing a serious flaw in their model.

    The complaint is that name-based labeling doesn't currently exist (and
    as Sean has stated that doesn't mean it _can't_ exist, just that it
    doesn't currently). In practice this has not been as big of an issue as
    you are making it out to be. Granted restorecond has a tiny race, and I
    wouldn't recommend using it on very security sensitive files but for
    usability having it relabel user_home_t to user_http_content_t isn't a
    problem (and causes no security issues).
