qemu-debootstrap - QEMU debootstrap wrapper SYNOPSIS
qemu-debootstrap [options] DESCRIPTION
The qemu-debootstrap wrapper calls debootstrap(8) making use of the --foreign and --second-stage options, and copies the appropriate qemu-user-static(1) binary into place in order to install cross-architecture chroots. In order for it to work seamlessly, the binfmt-sup- port package must be installed. SEE ALSO

grml-debootstrap - wrapper around debootstrap for installing plain Debian SYNOPSIS
grml-debootstrap [ options ] [IMAGE][1] [Screenshot] INTRODUCTION
grml-debootstrap is a wrapper suite around debootstrap (and cdebootstrap if you want) for installing a plain Debian system (e.g. via Grml) very fast and easy. All you have to do is adjust a few variables in the configuration file /etc/debootstrap/config or specify some command line options and invoke grml-debootstrap. If invoked without any configuration modifications or command line options a dialog based frontend will be available to control some basic configuration options. A plain and base Debian system will be installed on the given device, directory or virtual image file then. Customization of this process is possible as well. Caution The Grml team does not take responsibility for loss of any data! OPTIONS AND ENVIRONMENT VARIABLES
--arch architecture Set target architecture you want to install. Defaults to the architecture you are currently running. If you're running an amd64 kernel and want to deploy an i386 system use this option. Note: deploying amd64 from an i386 kernel does not work. Example: "--arch i386" --bootappend appendline-for-the-kernel Specify appendline for the kernel. E.g. "pci=nomsi" -c, --config file Use specified configuration file, defaults to /etc/debootstrap/config. --chroot-scripts directory Execute chroot scripts from specified directory. This allows customisation of the chroot setup, the executable script(s) present in the given directory are executed at the end of the chroot procedure. Default directory: /etc/debootstrap/chroot-scripts/ -d, --confdir path Place of configuration files for debootstrap, defaults to /etc/debootstrap. --debconf file Use specified file for preseeding Debian packages instead of using the default <confdir>/debconf-selections. --debopt params Extra parameters passed to the debootstrap command. --filesystem filesystem Filesystem that should be created when installing to a partition. If unset defaults to ext3. Valid values are all filesystems that can be created through mkfs.filesystem. --force Skip user acknowledgement and do not prompt for user input. --grmlrepos Enable's Debian repository ( via the /etc/apt/sources.list.d/grml.list configuration file. This provides the option to install Debian packages from Grml's repository. --grub device Device where grub should be installed to. Note that only the MBR (master boot record) can be used (/dev/sda, /dev/sdb,...). Partitions (like /dev/sda1, /dev/sdb2,...) are NOT supported because grub2 doesn't support installation into the PBR (partition boot record) anymore. Usage example: --grub /dev/sda. Note: just do not set this option to avoid installation of grub. --help, -h Show summary of options and exit. --hostname hostname Use specified hostname instead of the default (being grml). -i, --iso /mntpoint Specify mount point where you have a Debian ISO mounted loopback. Using this option instead of the mirror option gives you the possibility to install the base-system without network access. Make sure you mounted the according Debian-ISO to the given /mntpoint. See section Usage examples for a demonstration. --keep_src_list Do not overwrite user provided /etc/apt/sources.list. -m, --mirror URL Specify mirror which should be used for apt-get/aptitude. Corresponding with configuration variable MIRROR. --nodebootstrap Skip debootstrap, only do configuration to the target. --nopackages Skip installation of packages defined in /etc/debootstrap/packages. --nopassword Do not prompt for the root password. Note: Use the --password option if you want to set the root password during an automatic installation but don't want to use the interactive dialog. -p, --mntpoint /mntpoint Specify mount point that should be used for mounting the target system. Corresponding with configuration variable MNTPOINT. Note: this option has no effect if option -t is given and represents a directory. --packages file Use specified file as list for packages that should be installed instead of the default package list file <confdir>/packages. --password password Use specified password as password for user root. Use with caution, as your command line might be visible in the process list and the shell history. It's meant for automatic installation only. -r, --release releasename Specify release of new Debian system. Supported releases names: lenny, squeeze, wheezy (note: requires current version of debootstrap) and sid. Corresponding with configuration variable RELEASE. --pre-scripts directory Execute scripts from specified directory before executing the chroot script. This allows customisation of the system before the chroot has been set up. The environment variable $MNTPOINT is available inside the scripts for direct access of the chroot. Default directory: /etc/debootstrap/pre-scripts/ --scripts directory Execute scripts from specified directory. This allows customisation of the system after the chroot has been set up. The environment variable $MNTPOINT is available inside the scripts for direct access of the chroot. Default directory: /etc/debootstrap/scripts/ -t, --target target Target partition (/dev/...) or directory (anything else without /dev at the beginning). To install grub using --grub make sure to use a device instead of a directory as target (installation of grub as bootloader when using directories is NOT supported). -v, --verbose Increase verbosity. --vmfile Set up a Virtual Machine instead of installing to a partition or directory. This allows deployment of a Virtual Machine. The options needs to be combined with the --target option. Usage example: --vmfile --target /mnt/sda1/qemu.img --vmsize size Use specified size for size of Virtual Machine disk file. If not specified it defaults to 2G (being 2GB). Syntax as supported by qemu-img (see manpage qemu-img(1) for details. Usage example: --vmsize 3G -V, --version Show version of program and exit. Warning the command line parsing of grml-debootstrap does not validate the provided arguments for the command line options. Please be careful and check docs and /etc/debootstrap/config for further information. USAGE EXAMPLES
grml-debootstrap --target /dev/sda1 --grub /dev/sda Install default Debian release (wheezy) on /dev/sda1 and install bootmanager Grub in MBR (master boot record) of /dev/sda and use /dev/sda1 as system partition. grml-debootstrap --target /dev/sda6 --grub /dev/sda --release sid Install Debian unstable/sid on /dev/sda6, install bootmanager Grub in MBR (master boot record) of /dev/sda and use /dev/sda6 as system partition. mount /dev/sda1 /data/chroot grml-debootstrap --target /data/chroot Install default Debian release (wheezy) in directory /data/chroot (without any bootloader). grml-debootstrap --target /dev/sda3 --grub /dev/sda --mirror Install default debian release (wheezy) in a Virtual Machine file with 3GB disk size (including Grub as bootmanager in MBR of the virtual disk file): mount /dev/sda1 /mnt/sda1 grml-debootstrap --vmfile --vmsize 3G --target /mnt/sda1/qemu.img Install default Debian release (wheezy) on /dev/sda3 and install bootmanager Grub in MBR (master boot record) of /dev/sda and use /dev/sda3 as system partition. Use specified mirror instead of the default ( one. mount -o loop /mnt/sda6/debian-CD-1.iso /mnt/iso grml-debootstrap --target /dev/sda1 --grub /dev/sda --iso file:/mnt/iso/debian/ Install Debian on /dev/sda1 using the loopback mounted Debian-ISO for the base-system and install bootmanager Grub in MBR (master boot record) of /dev/sda and use /dev/sda1 as system partition. Please notice, that the chroot system requires network access for all packages which are not part of the ISO. FILES
/etc/debootstrap/config Main configuration file. You have to adjust it according to your needs if you want to execute grml-debootstrap in the non-interactive mode without any special command line arguments. /etc/debootstrap/chroot-script The script executed within the new Debian system as soon as the main system has been installed via [c]debootstrap. /etc/debootstrap/locale.gen Defines the default locales used for generating locales via locale-gen. /etc/debootstrap/packages Defines the software packages which should be installed in the new Debian system by default. /etc/debootstrap/extrapackages/ Debian Packages dropped in this directory will be installed into the new Debian system by default (Control variable: EXTRAPACKAGES) /etc/debootstrap/stages/ The default directory for storing information about executed stages. Every single function of grml-debootstrap will write done to the stages directory into a file named as the function itself if it has been executed successfully. You can adjust the location of the directory via configuration variable STAGES via /etc/debootstrap/config. Please notice that you have to remove the stages directory on your own if you want to re-execute grml-debootstrap after running it successfully once. This should avoid recurrent execution by error of grml-debootstrap (which might delete present data). CUSTOMIZATION
You can control execution of grml-debootstrap via adjusting /etc/debootstrap/config for some main stuff or via setting some selected variables via command line. The packages which should be installed in the new Debian system can be defined via the file /etc/debootstrap/packages. If you want to put existing files to the new Debian system you can place them into the (by default non-existing) directories boot, etc, share, usr and var in /etc/debootstrap/. Every existing directory will be copied to the new Debian system then. If you want to install additional packages that are not available via the Grml or Debian mirror drop them into /etc/debootstrap/extrapackages and make sure that EXTRAPACKAGES is set to "yes". AUTOMATIC INSTALLATION
If environment variable AUTOINSTALL is set grml-debootstrap can be executed in a full automatic mode. While this mode isn't really useful for interactive execution (just configure /etc/debootstrap/configure or specify the relevant variables on the command line instead) it is meant for use via boot option debian2hd on the Grml live system. The boot option debian2hd (more precise: the kernelname at the bootprompt) supports the following boot options (they correspond with the command line options mentioned above): target=... The target partition/directory of the new Debian system. Usage example: target=/dev/sda1 grub=... Where do you want to install grub to? Usage example: grub=/dev/sda release=... Specify release of new Debian system. Defaults to Debian wheezy. Supported relases: lenny, squeeze, wheezy and sid. Usage example: release=sid mirror=... Specify mirror which should be used for apt-get/aptitude instead of the default one ( Usage example: mirror= password=... Set password of user root without prompting for it but set it to the given argument. Usage example: password=AiTh5ahn Usage example for automatic installation: debian2hd target=/dev/sda1 grub=/dev/sda mirror= password=foobar You have to enter this command line at the bootprompt of the Grml live system. Please make sure that /dev/sda1 is the partition where you really want to install your new Debian system. Note Automatic installation within booting process is done in grml-autoconfig via setting environment variable AUTOINSTALL and creation of /usr/bin/grml-debootstrap_noninteractive with the available and relevant boot options for grml-debootstrap. SUPPORTED RELEASES
Current status: +----------------+-------------+-----------------+ | Release / Tool | debootstrap | cdebootstrap | +----------------+-------------+-----------------+ | Lenny | works [1] | works [1] | +----------------+-------------+-----------------+ | Squeeze | works | works | +----------------+-------------+-----------------+ | Wheezy | works | works | +----------------+-------------+-----------------+ | Sid | works [2] | works [2] | +----------------+-------------+-----------------+ lenny release [1] Please notice that lenny is the current old-stable release within Debian. grml-debootstrap can handle the release but you really should not use lenny anymore unless you really know what you are doing. Choose Debian 6.0 (squeeze) or Debian 7.0 (wheezy) instead. Notice that you need to specify a mirror providing the lenny release, the default ( doesn't provide it any longer nowadays. Set the mirror to e.g. if you don't have your own lenny mirror. When installing lenny to a new mdraid, grml-debootstrap will use md metadata format version 0.90. This limits the device to a maximum size of 2TB, but has the advantage of grub-legacy actually being able to boot from it. sid release [2] Please notice that sid is Debian/unstable and due to its nature might not be always installable. What might work instead is deploying a stable or testing release and upgrade it after installation finished. BUGS
