JohnGoerzen dfsbuild 1 John Goerzen dfsbuild Generate custom Debian From Scratch CD images dfsbuild -a arch -R -v | -V -c config_file -w working_dir &dfsbuild; is a program to generate Debian From Scratch (DFS) CD images. It is highly configurable and can generate images far different from the standard DFS image. The output from &dfsbuild; is an ISO image that is bootable on i386 and amd64, powerpc, or alpha systems. It uses Grub for the bootloader (on i386/amd64), and in the default configuration, generates DFS ISOs that are bootable and can be used to repair a Linux system or install a new one. &dfsbuild; requires about twice the eventual size of the ISO image to run. That is, if you are building a 600MB ISO image, you will need approximately 1.2GB free on the disk that holds working_dir. Configuration is accomplished through the config file given with -c. An example is available in /etc/dfsbuild/dfs.cfg. That example is commented and shows all the available options. dfsbuild must be run as root. These are the command-line options for &dfsbuild;. Please note that you must always specify at least -c and -w. -a architecture Specify the Debian architecture of the destination image. Normally, this defaults to the architecture of the host system. This option may be useful to, for instance, build an i386 image from your amd64 host. -c configfile Specifies the path for the configuration file to use. -R Resume an existing build. If your build failed, you may be able to restart it from where it left off by using this option. Resuming is not supported from every point, so do not be surprised if this option doesn't work for you everywhere. This option is still experimental and may disappear in future versions of dfsbuild. -v Enable verbose mode for dfsbuild messages only. -V Enable verbose mode for both dfsbuild messages and messages from external programs when possible. -w directory Specifies a directory for dfsbuild to use as its "work" directory. It will create its temporary files, and place the resulting ISO9660 image, in this directory. It is an error if this directory already exists, unless -R is given, in which case it is an error if this directory does not exist. dfsbuild, all associated scripts and programs, this manual, and all build scripts are Copyright © 2004-2006 John Goerzen.
