Yard is a suite of Perl scripts for creating rescue disks (also called bootdisks) for Linux. A rescue disk is a self-contained Linux kernel and filesystem on a floppy, usually used when you can't (or don't want to) boot off your hard disk. A rescue disk usually contains utilities for diagnosing and manipulating hard disks and filesystems.
bbiso is a shell script used to build a CD image for a bootable Linux system which runs entirely in RAM on an i386 PC platform. It is a rewrite and update of Philip Howard's bick package for making an image for a bootable Linux CD using Peter Anvin's syslinux. It consists of a configurable script plus required executables from other GPLed sources. It is oriented towards small target systems, and would usually run on a development host on which a filesystem image could be built.
btfs can be used as /init for constructing a run-time environment before running the real init. It supports extracting compressed (*.cgz, *.cbz2) and uncompressed (*.co) cpios located on a compile-defined directory (/). Also, it creates a tmpfs filesystem as the new root, if / isn't one already and the purpose of the initramfs isn't for starting a system in another location (disk, network, etc.). That will allow for the data on / to be swapped to disk when swap devices are activated later.
cdrtools (formerly cdrecord) creates home-burned CDs/DVDs with a CDR/CDRW/DVD/BluRay recorder. It works as a burn engine for several applications. It supports CD/DVD/BD recorders from many different vendors; all SCSI-3/mmc- and ATAPI/mmc-compliant drives should also work. Supported features include IDE/ATAPI, parallel port, and SCSI drives; audio CDs, data CDs, and mixed CDs; full multi-session support; CD-RWs, DVD-R/-RW, DVD+R/+RW, BD-R/BD-RE; and TAO, DAO, RAW, and human-readable error messages. cdrtools includes remote SCSI support and can access local or remote CD/DVD/BD writers.
cdvtoc is a simple utility for creating Solaris VTOC records suitable for building bootable CDs on Sun SPARC systems. The utility will create a VTOC that is aligned to cylinder boundaries and display the padding required for each component of the ISO. If required, the utility will stitch all the components together with the new VTOC to create your ISO file.
cfgsh is a configuration shell utility that is intended to be used for configuring embedded systems. It is meant to replace the normal combination of utilities including ifconfig, route, startup scripts, and configuration files with a single program that implements the same functionality in a manner more consistent with the embedded system world.
