     QCOWFS(8)                                               QCOWFS(8)

     NAME
          qcowfs - QCOW2 file system

     SYNOPSIS
          disk/qcowfs [ -n size ] [ -m mtpt ] [ -s service ] diskimage

     DESCRIPTION
          Qcowfs exposes a data file using the provided diskimage as
          the backing store.

          The -n flag truncates imagefile with the specified size (in
          bytes) before using it.  The -m flag sets the mtpt (default
          /mnt/qcow).  The -s flag causes qcowfs to post its 9P ser-
          vice as /srv/service.

     EXAMPLES
          Create a new QCOW2 diskimage and partition it

               disk/qcowfs -n $size image.qcow2
               disk/partfs /mnt/qcow/data
               disk/mbr -m /386/mbr /dev/sdXX/data
               disk/fdisk -baw /dev/sdXX/data
               disk/prep /dev/sdXX/plan9
