+# Where should Debian be installed to?
+# Usually you want to use a partition.
+# If you specify a string *without* /dev/ in the beginning, grml-debootstrap
+# assumes you want to install Debian into a directory. MKFS, TUNE2FS, GRUB and
+# FSCK will be ignored.
+# Make sure the TARGET-directory points to a filesystem which has the dev, exec
+# options enabled.
+# Default: no default.
+# Usage examples:
+# TARGET='/dev/sda1' # install to partition /dev/sda1
+# TARGET='/mnt/grml' # install into directory /mnt/grml
+
+# Install the grub bootloader?
+# Default: 'yes'
+# Usage example:
+# GRUB_INSTALL='no' # Do not install the grub bootloader.
+
+# Specify the device where grub will be installed.
+# Note: grub can not be installed into a partition.
+# Default: no default. (Grub will not be installed.)
+# Usage example:
+# GRUB='/dev/sda' # Install into MBR of sda
+
+# Additional kernel boot options. (For grub.)
+# Default: no default.
+# Usage example:
+# BOOT_APPEND='pci=nomsi'
+
+# Set mirror where packages will be downloaded from.
+# Default: use /etc/debootstrap/etc/apt/sources.list if it exists, else
+# 'http://deb.debian.org/debian'
+# Usage example:
+# MIRROR='ftp://ftp.de.debian.org/debian'
+
+# Debian Install CD path:
+# If you have a Debian CD (or mounted ISO), core packages will be
+# installed from the CD instead of from the network.
+# Default: no default.
+# ISO='file:/mnt/iso/debian/'
+
+# If /etc/apt/sources.list should NOT be build on the fly, this
+# options allows providing a separate apt sources.list file via
+# /etc/debootstrap/etc/apt/sources.list
+# KEEP_SRC_LIST='yes'
+
+# To enable the Grml repository via /etc/apt/sources.list.d/grml.list
+# set this variable to 'yes'.
+# Default: 'no'
+# GRMLREPOS='yes'
+
+# Install packages from grml-repository?
+# Requires activated $GRMLREPOS from above. If empty nothing will be added.
+# Default: no default.
+# GRMLPACKAGES='grml-etc-core'
+
+# To enable Debian's backports repository via
+# /etc/apt/sources.list.d/backports.list set this variable to 'yes'.
+# Default: 'no'
+# BACKPORTREPOS='yes'
+
+# Debian release that should be installed.
+# Supported values: lenny, squeeze, wheezy, jessie, stretch, buster, bullseye, sid
+# Default: 'buster'
+# RELEASE='buster'
+
+# Define components that should be used within sources.list.
+# Default: 'main'
+# COMPONENTS='main contrib non-free'
+
+# Set target architecture.
+# Only useful when installing i386 while running an amd64 kernel.
+# Default: current architecture. (From 'dpkg —print-architecture'.)
