       grml-debootstrap [ options ]

       [IMAGE][1] [Screenshot]


       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 configuration file /etc/debootstrap/config
       (or specify some variables via command line) and invoke grml-debootstrap without any
       further options then.

       A plain and base Debian system will be installed on the given device (or directory) then.
       Customization of this process is possible as well.

           The Grml team does not take responsibility for loss of any data!


       --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

       --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.

           Skip user acknowledgement and do not prompt for user input.

           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.

           Do not download and check signatures for retrieved Release files.

           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.

           Skip debootstrap, only do configuration to the target.

           Skip installation of packages defined in /etc/debootstrap/packages.

           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:

       -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

       -v, --verbose
           Increase verbosity.

           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.

           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.


           grml-debootstrap --target /dev/sda1 --grub /dev/sda

       Install default Debian release (stable/squeeze) 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 (stable/squeeze) in directory /data/chroot (without any

           grml-debootstrap --target /dev/sda3 --grub /dev/sda  --mirror

       Install default debian release (stable/squeeze) 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 (stable/squeeze) 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-40r0-i386-CD-1.iso /mnt/iso
           grml-debootstrap --target /dev/sda1 --grub /dev/sda --iso file:/mnt/iso/debian/

       Install Debian stable/squeeze 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.



       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


       The script executed within the new Debian system as soon as the main system has been
       installed via [c]debootstrap.


       Defines the default locales used for generating locales via locale-gen.


       Defines the software packages which should be installed in the new Debian system by


       Debian Packages dropped in this directory will be installed into the new Debian system by
       default (Control variable: EXTRAPACKAGES)


       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).


       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".


       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. The boot option debian2hd (more
       precise: the kernelname on bootprompt) supports the following boot options (they
       correspond with the command line options mentioned above):


       The target partition/directory of the new Debian system. Usage example: target=/dev/sda1


       Where do you want to install grub to? Usage example: grub=/dev/sda


       Specify release of new Debian system. Defaults to Debian squeeze. Supported relases:
       lenny, squeeze, wheezy and sid. Usage example: release=sid


       Specify mirror which should be used for apt-get/aptitude instead of the default one
       ( Usage example: mirror=


       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

           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.


       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 stable (squeeze) instead.

           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 stable (squeeze) or testing
           (wheezy) and upgrade it after installation finished.


       Probably. Please send bugreports to Michael Prokop <[2]>.
