    Aha - so Hans want open() to work on directories only when app does

    open("/etc", O_OPEN_DIRECTORY_AS_FILE)

    ? That will not break anything, but I doubt it is better than

    open("/etc#opendirasfile", O_RDONLY)

    which has advantage of easily going through network, advantage of user
    being able to explicitly ask for this even for old apps (think cat
    /etc - how do you convince cat to use O_OPEN_DIRECTORY_AS_FILE? You
    add option? And why adding option when cat /etc#opendirasfile works

    PS: The latter complete with syntax has one advantage: it is already
    implemented ;-).

    PPS: Hans, please try not to change subject lines in every
    posting. The whole thread is much easier to kill that way :-).
