I think
  perl -e 'print grep m[/horseradish],`mount`'
is hard to beat for its simplicity.  Note I'm using Perl's
built-in grep; there's no need to run the system's grep.

You can code something like
  --------------------------------
  if( grep m[/horseradish],`mount` ){
    useMountedHorseradish();
  }else{
    dealWithUnmountedHorseradish();
  }
  --------------------------------
because Perl's grep will return an empty string if 'horseradish'
isn't found in `mount`, and an empty string is logically false,
whereas any nonempty string is logically true.
