NAME # rdsetroot - insert disk image into RAMDISK kernel
SYNOPSIS # rdsetroot -s kernel
rdsetroot [-dx] kernel [disk.fs]
DESCRIPTION # The rdsetroot utility inserts the file disk.fs into the reserved space inside a RAMDISK kernel. If disk.fs is not specified, rdsetroot reads from standard input.
The options are as follows:
-d
Debug.
-s
Print the size in bytes of the reserved space in the RAMDISK kernel.

SCAN_FFS(8) - System Manager’s Manual # SCAN_FFS(8) - System Manager’s Manual
NAME # scan_ffs - find UFS/FFS partitions on a disk
SYNOPSIS # scan_ffs [-lsv] [-b begin] [-e end] device
DESCRIPTION # This is the life-saver of typos. If you have ever been working too long, and just happened to type ‘disklabel -w sd0 floppy’, instead of ‘disklabel -w fd0 floppy’, you know what I am talking about.
This little program will take a raw disk device (which you might have to create) that covers the whole disk, and finds all probable UFS/FFS partitions on the disk.

NAME # sd - SCSI disk driver
SYNOPSIS # sd* at scsibus? #sd0 at scsibus0 target 3 lun 0 (fixed-configuration example)
DESCRIPTION # The sd driver provides support for a SCSI disk. It allows the disk to be divided up into a set of pseudo devices called partitions. In general the interfaces are similar to those described by wd(4).

NAME # softraid - software RAID
SYNOPSIS # softraid0 at root
DESCRIPTION # The softraid device emulates a Host Bus Adapter (HBA) that provides RAID and other I/O related services. The softraid device provides a scaffold to implement more complex I/O transformation disciplines. For example, one can tie chunks together into a mirroring discipline. There really is no limit on what type of discipline one can write as long as it fits the SCSI model.
