FLASHFS(4)                                             FLASHFS(4)

     NAME
          flashfs - journalling file system for flash memory

     SYNOPSIS
          aux/flashfs [ -Dr ] [ -n nsect ] [ -z sectsize ] [ -f file ]
          [ -m mountpoint ]

     DESCRIPTION
          Flashfs interprets the journal-based file system created by
          mkflashfs(8) and stored in file (default /dev/flash/fs) so
          that it can be mounted into a Plan 9 file system.  Flashfs
          is typically used to create a stand alone file system from a
          small persistent storage device, such as an erasable flash
          memory.  It does not authenticate its clients and assumes
          each group has a single member with the same name.

          The -s option causes flashfs to post its channel on
          #s/flashfs.  Flashfs mounts itself on mountpoint (default
          /n/brzr).  The -D option turns on 9P debugging output.  The
          -r option makes the file system read-only.

          The files and directory structure are divided into sectsize
          (default 4096) byte blocks.  Larger blocks make large files
          more compact but take longer to access.  Supplying the -n
          option forces file to contain exactly nsect sectors.
