VND(4)                    NetBSD Programmer's Manual                    VND(4)

NAME
     vnd - vnode disk driver

SYNOPSIS
     pseudo-device vnd [count]

DESCRIPTION
     The vnd driver provides a disk-like interface to a file.  This is useful
     for a variety of applications, including swap files and building miniroot
     or floppy disk images.

     This document assumes that you're familiar with how to generate kernels,
     how to properly configure disks and pseudo-devices in a kernel configura-
     tion file.

     In order to compile in support for the vnd, you must add a line similar
     to the following to your kernel configuration file:

           pseudo-device  vnd  4    # vnode disk driver

     The count argument is how many vnds memory is allocated for at boot time.
     In this example, no more than 4 vnds may be configured.

     There is a run-time utility that is used for configuring vnds.  See
     vnconfig(8) for more information.

FILES
     /dev/{,r}vnd*  vnd device special files.

SEE ALSO
     MAKEDEV(8), config(8), fsck(8), mount(8), newfs(8), vnconfig(8)

HISTORY
     The vnode disk driver was originally written at the University of Utah.

BUGS
     The vnd driver does not work if the file does not reside in a local
     filesystem.
