    # directory, so if available, '-M' prevents that, and if it is
    # an invalid option, then simply not using '-m' will usually 
    # do the trick.  We have to watch the exit status of this script,
    # so, the last command run should have somthing to do with the valid
    # creation of the "fax" user.
