NEWFS_SYSVBFS(8)

NAME
newfs_sysvbfs - construct a new System V Boot File System

SYNOPSIS
newfs_sysvbfs [-FZ] [-s sectors] special

DESCRIPTION
newfs_sysvbfs builds a System V boot file system on the specified special. If it is a device, the size information will be taken from the disk label and before running newfs_sysvbfs the disk must be labeled using disklabel(8); the proper fstype is “SysVBFS”. Otherwise, the size must be specified on the command line.

The following arguments are supported:

-F  Create file system to a regular file.

-s sectors
    Create file system with specified number of disk sectors.

-Z  Fill file with zeroes instead of creating a sparse file.

HISTORY

BUGS
The sysvbfs support is still experimental and there are few sanity checks.
