+
+# 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/hda or
+# /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/sda
+# 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 lvm
+
+# 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, /usr, /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 \
+# boot-root :: \
+# 40 50 100 ext3 \
+# $primary{ } $bootable{ } \

+# .
+
+# The full recipe format is documented in the file partman-auto-recipe.txt
+# included in the 'debian-installer' package or available from D-I source
+# repository. This also documents how to specify settings such as file
+# system labels, volume group names and which physical devices to include
+# in a volume group.

+# This makes partman automatically partition without confirmation, provided
+# that you told it what to do using one of the methods above.

+
+## Partitioning using RAID
+# The method should be set to "raid".
+#d-i partman-auto/method string raid
+# Specify the disks to be partitioned. They will all get the same layout,
+# so this will only work if the disks are the same size.
+#d-i partman-auto/disk string /dev/sda /dev/sdb
+
+# Next you need to specify the physical partitions that will be used.
+#d-i partman-auto/expert_recipe string \

+# 1000 5000 4000 raid \
+# $primary{ } method{ raid } \

+# method{ raid } \
+# . \
+# 500 10000 1000000000 raid \
+# method{ raid } \
+# .
+
+# Last you need to specify how the previously defined partitions will be
+# used in the RAID setup. Remember to use the correct partition numbers
+# for logical partitions. RAID levels 0, 1, 5, 6 and 10 are supported;
+# devices are separated using "#".
+# Parameters are:
+# <raidtype> <devcount> <sparecount> <fstype> <mountpoint> \
+# <devices> <sparedevices>
+
+#d-i partman-auto-raid/recipe string \
+# 1 2 0 ext3 / \

+# .
+
+# For additional information see the file partman-auto-raid-recipe.txt
+# included in the 'debian-installer' package or available from D-I source
+# repository.

+# This makes partman automatically partition without confirmation.

+d-i partman/choose_partition select finish
+d-i partman/confirm boolean true

+## Controlling how partitions are mounted

+# 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
