+## Partitioning example
+# If the system has free space you can choose to only partition that space.
+# This is only honoured if partman-auto/method (below) is not set.
+d-i partman-auto/init_automatically_partition select biggest_free
+
+# Alternatively, you may specify a disk to partition. If the system has only
+# one disk the installer will default to using that, but otherwise the device
+# name must be given in traditional, non-devfs format (so e.g. /dev/sda
+# and not e.g. /dev/discs/disc0/disc).
+# For example, to use the first SCSI/SATA hard disk:
+d-i partman-auto/disk string /dev/vda
+# In addition, you'll need to specify the method to use.
+# The presently available methods are:
+# - regular: use the usual partition types for your architecture
+# - lvm:     use LVM to partition the disk
+# - crypto:  use LVM within an encrypted partition
+d-i partman-auto/method string regular
+
+# If one of the disks that are going to be automatically partitioned
+# contains an old LVM configuration, the user will normally receive a
+# warning. This can be preseeded away...
+d-i partman-lvm/device_remove_lvm boolean true
+# The same applies to pre-existing software RAID array:
+d-i partman-md/device_remove_md boolean true
+# And the same goes for the confirmation to write the lvm partitions.
+d-i partman-lvm/confirm boolean true
+d-i partman-lvm/confirm_nooverwrite boolean true
+
+# You can choose one of the three predefined partitioning recipes:
+# - atomic: all files in one partition
+# - home:   separate /home partition
+# - multi:  separate /home, /var, and /tmp partitions
+d-i partman-auto/choose_recipe select atomic
+
+# Or provide a recipe of your own...
+# If you have a way to get a recipe file into the d-i environment, you can
+# just point at it.
+#d-i partman-auto/expert_recipe_file string /hd-media/recipe
+
+# If not, you can put an entire recipe into the preconfiguration file in one
+# (logical) line. This example creates a small /boot partition, suitable
+# swap, and uses the rest of the space for the root partition:
+#d-i partman-auto/expert_recipe string                         \

+## Controlling how partitions are mounted
+# The default is to mount by UUID, but you can also choose "traditional" to
+# use traditional device names, or "label" to try filesystem labels before
+# falling back to UUIDs.
+#d-i partman/mount_style select uuid
+
+### Base system installation
+# Configure APT to not install recommended packages by default. Use of this
+# option can result in an incomplete system and should only be used by very
+# experienced users.
+#d-i base-installer/install-recommends boolean false
+

+# Uncomment this if you don't want to use a network mirror.

+# but sending reports helps the project determine what software is most
+# popular and include it on CDs.
+#popularity-contest popularity-contest/participate boolean false
+
+### Boot loader installation
+# Grub is the default boot loader (for x86). If you want lilo installed
+# instead, uncomment this:
+#d-i grub-installer/skip boolean true
+# To also skip installing lilo, and install no bootloader, uncomment this
+# too:
+#d-i lilo-installer/skip boolean true
+
+
+# This is fairly safe to set, it makes grub install automatically to the MBR
+# if no other operating system is detected on the machine.
+d-i grub-installer/only_debian boolean true
+
+# This one makes grub-installer install to the MBR if it also finds some other
+# OS, which is less safe as it might not be able to boot that other OS.
+d-i grub-installer/with_other_os boolean true
+
+# Due notably to potential USB sticks, the location of the MBR can not be
+# determined safely in general, so this needs to be specified:
+#d-i grub-installer/bootdev  string /dev/sda
+# To install to the first device (assuming it is not a USB stick):
+#d-i grub-installer/bootdev  string default
+
+# Alternatively, if you want to install to a location other than the mbr,
+# uncomment and edit these lines:
+#d-i grub-installer/only_debian boolean false
+#d-i grub-installer/with_other_os boolean false
+#d-i grub-installer/bootdev  string (hd0,1)

+# Optional password for grub, either in clear text
+#d-i grub-installer/password password r00tme

+# or encrypted using an MD5 hash, see grub-md5-crypt(8).
+#d-i grub-installer/password-crypted password [MD5 hash]
+
+# Use the following option to add additional boot parameters for the
+# installed system (if supported by the bootloader installer).
+# Note: options passed to the installer will be added automatically.
+#d-i debian-installer/add-kernel-opts string nousb
+
+### Finishing up the installation
+# During installations from serial console, the regular virtual consoles
+# (VT1-VT6) are normally disabled in /etc/inittab. Uncomment the next
+# line to prevent this.
+#d-i finish-install/keep-consoles boolean true
+
+# Avoid that last message about the install being complete.
+d-i finish-install/reboot_in_progress note
+
+# This will prevent the installer from ejecting the CD during the reboot,
+# which is useful in some situations.
+#d-i cdrom-detect/eject boolean false
+
+# This is how to make the installer shutdown when finished, but not
+# reboot into the installed system.
+#d-i debian-installer/exit/halt boolean true
+# This will power off the machine instead of just halting it.
+#d-i debian-installer/exit/poweroff boolean true
+
+### Preseeding other packages
+# Depending on what software you choose to install, or if things go wrong
+# during the installation process, it's possible that other questions may
+# be asked. You can preseed those too, of course. To get a list of every
+# possible question that could be asked during an install, do an
+# installation, and then run these commands:
+#   debconf-get-selections --installer > file
+#   debconf-get-selections >> file
+
+
+#### Advanced options
+### Running custom commands during the installation
+# d-i preseeding is inherently not secure. Nothing in the installer checks
+# for attempts at buffer overflows or other exploits of the values of a
+# preconfiguration file like this one. Only use preconfiguration files from
+# trusted locations! To drive that home, and because it's generally useful,
+# here's a way to run any shell command you'd like inside the installer,
+# automatically.
+
+# This first command is run as early as possible, just after
+# preseeding is read.
+#d-i preseed/early_command string anna-install some-udeb
+# This command is run immediately before the partitioner starts. It may be
+# useful to apply dynamic partitioner preseeding that depends on the state
+# of the disks (which may not be visible when preseed/early_command runs).
+#d-i partman/early_command \
+#       string debconf-set partman-auto/disk "$(list-devices disk | head -n1)"
+# This command is run just before the install finishes, but when there is
+# still a usable /target directory. You can chroot to /target and use it
+# directly, or use the apt-install and in-target commands to easily install
+# packages and run commands in the target system.
+#d-i preseed/late_command string apt-install zsh; in-target chsh -s /bin/zsh
