    Guys - I think you are missing an easier solution.
    Correct me if I am wrong, but I think the problem you are solving is this:
    There is an ethernet connection to an ISP, and all you want to do is run
    a script to restart services whenever that interface is brought up.

    If that is the case just make a script /sbin/ifup-local that checks
    whether the sole argument is the interface you care about, and if so,
    performs the restarts.

    Actually I like to put the ifup-local script in
    /etc/sysconfig/network-scripts and add a symbolic link to it from
    /sbin/ifup-local. That way I can keep my script in the same location as
    the interface configurations.

    Here is a sample script I used to set system time whenever an on-demand
    ppp0 interface was started:
    ---------------------------------------------------------------
    #!/bin/bash
    #Invoked from ifup-post via /sbin/ifup-local ${DEVICE}
    #The installer must add a symbolic link from /sbin/ifup-local to this script
    if [ $1 = "ppp0" ] ; then
      ntpdate=`ntpdate tock.usno.navy.mil 2>&1`
      ntprc=$?
      logger "ifup-local: $ntpdate"
      if [ $ntprc -eq 0 ] ; then
        clock -w
        logger "ifup-local: clock -w performed"
      fi
    fi
    ---------------------------------------------------------------
