+### Partitioning
+# 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/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 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
+
+#d-i     partman/default_filesystem                     string ext3
+#d-i     partman/choose_partition                       select finish
+
+# 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
+
+# Just in case, the positive answer to all other imagineable conformation questions:
+#d-i     partman-partitioning/confirm_write_new_label   boolean true
+#d-i     partman/confirm                                boolean true
