startup scripts: get rid of $* and replace it with properly quoted "$@"

In shell scripts an unquoted $* is rarely useful, for example because it breaks
in presence of file names with spaces.

  Use "$@" unless you have a specific reason to use $*.

  Short answer: use "$@" (note the double quotes). The other forms are very
  rarely useful.
