NAME

di-netboot-assistant - Debian-Installer netboot assistant

SYNOPSIS

di-netboot-assistant {install | uninstall | uncache | purge | fw-toggle} image ... [ --alias= alias ] [ --arch= arch ] [ --di-args= ARGS ] [ --ignore-sig ] [ --target-args= ARGS ] [ --offline ] [ --verbose ]
di-netboot-assistant {rebuild-grub | rebuild-menu} [ --verbose ]
di-netboot-assistant { -h | --help } | { -V | --version }

DESCRIPTION

di-netboot-assistant is a tool to download and extract Debian Installer netboot images.

Unless the -h , --help , -V , or --version option is given, one of the following commands must be present.

install

install is followed by a repository name desired for installation. The repository name has to be one of those declared in /etc/di-netboot-assistant/di-sources.list . The image will be installed/extracted in the default location (declared in /etc/di-netboot-assistant/di-netboot-assistant.conf ).

uninstall

uninstall is followed by the name of the repository to be uninstalled (or the repository’s alias if you used --alias= ). The netboot files related to that distribution will be removed from the TFTP server.

uncache

uncache will clean the cached files for the given netboot image. You must specify a repository name (not an --alias= name).

purge

purge is followed by a repository name desired for installation. purge is identical to running uninstall then uncache for a given repository.

rebuild-grub

rebuild-grub will rebuild the grub EFI netboot image. The configuration itself is set up by rebuild-menu . This command takes no argument.

rebuild-menu

rebuild-menu will rebuild the top level menu. It is useful if you have modified di-netboot-assistant.conf or added a Live ISO image. The installer images need to have a top level menu (like i386, amd64). This command takes no argument.

fw-toggle

fw-toggle is followed by a repository name and adds respectively removes non-free firmware. The non-free firmware will be downloaded if not available from cache. Use n-pkg as repository to add the firmware to packaged installer images.

OPTIONS

-h , --help Print short help and exit
-V , --version

Print script version and exit

--alias= alias

Specify the alias name under which this repository will be saved. Alias names can only contain alphanumeric, "_" and "-" characters. This is especially useful for daily images. By default, the alias name is the same as the repository name.

--arch= arch

Specify the architecture to operate on. The architecture used for the install action must be declared in /etc/di-netboot-assistant/di-sources.list . Architectures available for the purge action are those previously installed. Available architectures can be listed by leaving --arch= empty. If absent, the system’s architecture (as reported by dpkg --print-architecture) is used.

--verbose

Verbose messages

--di-args= " ARGS "

Debian-Installer boot arguments. The specified arguments will be *appended* to the one provided in the downloaded image, before the "--". (You can also define DI_ARGS= in di-netboot-assistant.conf ).

--tftproot= " DIR "

Overwrite the TFTP_ROOT variable given in the configuration. Use DIR as the TFTP server’s root directory instead. Not recommended and to be used with care, as only a single TFTP root directory is supported.

--ignore-sig

Ignore failing image signature checks. Useful when run non-interactively in scripts and images are known to be not signed.

--target-args= " ARGS "

Boot arguments for the target (installed) system. The specified arguments will be *appended* to the one provided in the downloaded image, at the very end of the line. (You can also define TARGET_ARGS= in di-netboot-assistant.conf ).

--offline

Don’t download the files (use the files cached previously).

EXAMPLES

To install a netboot image for the stable repository, for the default architecture:

di-netboot-assistant install stable

To list the installed netboot images that can be removed:

di-netboot-assistant purge

To remove a netboot image for the stable repository, for the default architecture:

di-netboot-assistant purge stable

To toggle firmware for the stable repository, for the default architecture:

di-netboot-assistant fw-toggle stable

To toggle firmware for packaged debian-installer netboot images, all architectures:

di-netboot-assistant fw-toggle n-pkg --arch=all

EXIT CODE

0

Successful program execution.

1

An error occurred. (Note that purge doesn’t fail if the specified repository doesn’t exists).

FILES

/etc/di-netboot-assistant/di-netboot-assistant.conf

The default system-wide configuration file. The file syntax must be bash(1) compatible.

˜/.di-netboot-assistant/di-netboot-assistant.conf

User’s own configuration file. The file syntax must be bash(1) compatible. (See file peruser.di-netboot-assistant.conf, in /usr/share/doc/di-netboot-assistant/examples/).

/etc/di-netboot-assistant/di-sources.list

This file contains the list of downloadable netboot images.

/etc/di-netboot-assistant/pxelinux.HEAD

The content of this file is prepended to the generated PXElinux config file (i.e boot menu). PXElinux bootloader is used on BIOS based i386 and amd64 systems.

/var/lib/di-netboot-assistant/

The folder where hints about installed netboot images are stored. Do not edit those files, re-use install to modify the settings of installed image.

/var/cache/di-netboot-assistant/

The folder where downloaded files are stored (cached) before "installing" them. Use the action uncache to remove cached files.

SECURITY

Do not use sudo to grant execution right to di-netboot-assistant (see the README file).

PROXY

di-netboot-assistant uses wget or curl to actually download the files. You can set the environnement variables accordingly.
