Usage example: /dev/sda --efi Target for EFI installation. Usage example: /dev/sda1 --arch Set target architecture, use for installing i386 on amd64. --filesystem Filesystem that should be used when target is a partition or Virtual Machine (see --vmfile). --force Do not prompt for user acknowledgement. Options for Virtual Machine deployment: --vm Set up a Virtual Machine on an existing block device instead of plainly installing to a partition or directory. Needs to be combined with --target. Example: --vm --target /dev/mapper/your-vm-disk --vmfile Like --vm, but install into a regular file (created by 'qemu-img create -f raw ...') instead. Example: --vmfile --target /mnt/sda1/qemu.img --vmsize Use specified size for size of VM file (default: 2G). Syntax as supported by qemu-img, like: --vmsize 3G Configuration options: -c, --config Use specified configuration file, defaults to /etc/debootstrap/config -d, --confdir Place of config files for debootstrap, defaults to /etc/debootstrap --packages Install packages defined in specified list file instead of using /etc/debootstrap/packages. --nopackages Skip installation of packages defined in /etc/debootstrap/packages --nokernel Skip installation of default kernel images. --nointerfaces Do not copy /etc/network/interfaces from host system to target system. (This option is automatically enabled when using --vmfile.) --defaultinterfaces Install a default /etc/network/interfaces file (enabling DHCP for eth0) instead of taking over config from host system. --debconf Pre-seed packages using specified pre-seed db file. --grmlrepos Enable Grml's Debian repository (deb.grml.org). --backportrepos Enable Debian's backports repository (backports.debian.org). --keep_src_list Do not overwrite user provided apt sources.list. --contrib Enable 'contrib' in COMPONENTS (defaults to 'main' only). --non-free Enable non-free in COMPONENTS (defaults to 'main' only). --hostname Hostname of Debian system. --nopassword Do not prompt for the root password. --password Use specified password as password for user root. --sshcopyid Use locally available public keys to authorise root login on the target system. --bootappend Add specified appendline to kernel whilst booting. --chroot-scripts Execute chroot scripts from specified directory. --pre-scripts Execute scripts from specified directory (before chroot-scripts). --scripts Execute scripts from specified directory (after chroot-scripts). --remove-configs Delete grml-debootstrap configuration files from installed system. Other options: -v, --verbose Increase verbosity. --debug Execute in very verbose way. -h, --help Print this usage information and exit. -V, --version Show summary of options and exit.
