   NAME
         dcopy (generic) - copy file systems for optimal access time

   SYNOPSIS
         dcopy [-F FSType] [-V] [current_options] [-o specific_options]
         inputfs outputfs

   DESCRIPTION
         dcopy copies file system inputfs to outputfs.  inputfs is the device
         file for the existing file system; outputfs is the device file to
         hold the reorganized result.  For the most effective optimization
         inputfs should be the raw device and outputfs should be the block
         device.  Both inputfs and outputfs should be unmounted file systems.

         current_options are options supported by the s5-specific module of
         dcopy.  Other FSTypes do not necessarily support these options.
         specific_options indicate suboptions specified in a comma-separated
         list of suboptions and/or keyword-attribute pairs for interpretation
         by the FSType-specific module of the command.

         The options are:

         -F        Specify the FSType on which to operate.  The FSType should
                   either be specified here or be determinable from
                   /etc/vfstab by matching the inputfs (device) with an entry
                   in the table.

         -V        Echo the complete command line, but do not execute the
                   command.  The command line is generated by using the
                   options and arguments provided by the user and adding to
                   them information derived from /etc/vfstab.  This option
                   should be used to verify and validate the command line.

         -o        Specify FSType-specific options.

   NOTE
         This command may not be supported for all FSTypes.
