The following is a demonstration of cdrewind, run as a regular
user on a Solaris server which is running the Volume Management
daemon "vold". Here we rewind the CDROM before ejection,

   $ cdrewind -v /vol/dev/aliases/cdrom0 
   CDROM rewound successfully.
   $ eject cdrom


Now we kill vold as root,

   # pkill -V

such that we can demonstrate cdrewind without vold running,

   # cdrewind -v /dev/dsk/c0t1d0s2
   CDROM rewound successfully.
