     PARTFS(8)                                               PARTFS(8)

     NAME
          partfs - serve file, with partitions

     SYNOPSIS
          disk/partfs [ -Dr ] [ -d diskname ] [ -m mtpt ] [ -p 9load-
          parts ] [ -s srvname ] diskimage

     DESCRIPTION
          Partfs presents the file diskimage in the manner of sd(3) on
          mtpt/diskname (default /dev/sdXX).  Changes made to the disk
          are written through to diskimage unless the -r option is
          given.

          When setting disk geometry with the geometry control mes-
          sage, the arguments are sectors and sector size.

          The -m option causes partfs to mount its synthetic file sys-
          tem at mtpt instead of /dev.

          The -p option causes partfs to treat 9load-parts as a parti-
          tion environment variable constructed by 9load (see
          9boot(8)) and adds the defined partitions.  This is used
          primarily by boot(8) to assist booting from USB disks.

          The -s option causes partfs to post its 9P service at
          /srv/service.

     EXAMPLES
          Partition a USB flash device:

               disk/partfs /dev/sdU0.0/data
               disk/mbr -m /386/mbr /dev/sdXX/data
               disk/fdisk -baw /dev/sdXX/data
               disk/prep /dev/sdXX/plan9
