+# 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 regular
+
+# You can define the amount of space that will be used for the LVM volume
+# group. It can either be a size with its unit (eg. 20 GB), a percentage of
+# free space or the 'max' keyword.
+d-i partman-auto-lvm/guided_size string max
+
+# 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                         \

+### 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
+d-i preseed/late_command string \
+	in-target wget -P /tmp/ http://{{ provision_fqdn }}/late-command.sh; \
