    These are not dependencies but "only" the sequence of startup (and it is
    not only Debian but also Fedora/RedHat, SuSE, Mandrake and probably all
    except Gentoo).
    Yuo get a much stricter ordering and sorting (and thus much simpler to
    implement in a shell script).

    This would be a win (especially if the numbers are tweked to tune this)
    with a relatively small effort.
    However for real dependencies and parallelism you want the info similar
    to creat a Makefile from it (i.e. the explicit dependency from service X
    to service Y). As a consequence you can get rid of the numbers (since
    they are not needed any more).
