    Theres some truth. And its really arguably, but I think, I see your point.

    And taking on the situation with reiser4 with "smartmost VFS" approach,
    time should pass and with time and expirience on hands it will be evident what
    should go in VFS. Now its may be too early.

    Considering "amazing PR skills" of Hans Reiser it was the only viable way
    to get this changes in VFS. Cause, ironically, mr. Hellwig that currently
    demand it to be scrapped out or go in VFS would instakill Hans Reiser
    (i know many people would:) if he only touched holy cow of VFS for any
    reiser4 purpose.

    As I told before, some technically right things just do not work in this
    imperfect world. You have to count with social issues, and Hans Reiser
    wont, he just avoid them whenever its possible.
