Using preseeding to partition the harddisk is very much limited to what is supported by <classname>partman-auto</classname>. You can choose to partition either existing free space on a disk or a whole disk. The layout of the disk can be determined by using a predefined recipe, a custom recipe from a recipe file or a recipe included in the preconfiguration file. It is currently not possible to partition multiple disks using preseeding.

134.

The identification of disks is dependent on the order in which their drivers are loaded. If there are multiple disks in the system, make very sure the correct one will be selected before using preseeding.

135.

# If the system has free space you can choose to only partition that space.
#d-i partman-auto/init_automatically_partition select biggest_free

# Alternatively, you can specify a disk to partition. The device name must
# be given in traditional non-devfs format.
# Note: A disk must be specified, unless the system has only one disk.
# 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", "lvm" and "crypto"
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

# 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...
# The recipe format is documented in the file devel/partman-auto-recipe.txt.
# 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{ } \
# method{ format } format{ } \
# use_filesystem{ } filesystem{ ext3 } \
# mountpoint{ /boot } \
# . \
# 500 10000 1000000000 ext3 \
# method{ format } format{ } \
# use_filesystem{ } filesystem{ ext3 } \
# mountpoint{ / } \
# . \
# 64 512 300% linux-swap \
# method{ swap } format{ } \
# .

# This makes partman automatically partition without confirmation, provided
# that you told it what to do using one of the methods above.
d-i partman/confirm_write_new_label boolean true
d-i partman/choose_partition select finish
d-i partman/confirm boolean true

Partitioning using RAID

137.

You can also use preseeding to set up partitions on software RAID arrays. Supported are RAID levels 0, 1, 5, 6 and 10, creating degraded arrays and specifying spare devices. If you are using RAID 1, you can preseed grub to install to all devices used in the array; see <xref linkend="preseed-bootloader"/>.

138.

This type of automated partitioning is easy to get wrong. It is also functionality that receives relatively little testing from the developers of &d-i;. The responsibility to get the various recipes right (so they make sense and don't conflict) lies with the user. Check <filename>/var/log/syslog</filename> if you run into problems.

139.

# NOTE: this option is of beta release quality and should be used carefully

# 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/discs/disc0/disc /dev/discs/disc1/disc

# Next you need to specify the physical partitions that will be used.
#d-i partman-auto/expert_recipe string \
# multiraid :: \
# 1000 5000 4000 raid \
# $primary{ } method{ raid } \
# . \
# 64 512 300% 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.
# Parameters are:
# &lt;raidtype&gt; &lt;devcount&gt; &lt;sparecount&gt; &lt;fstype&gt; &lt;mountpoint&gt; \
# &lt;devices&gt; &lt;sparedevices&gt;
# RAID levels 0, 1, 5, 6 and 10 are supported; devices are separated using "#"
#d-i partman-auto-raid/recipe string \
# 1 2 0 ext3 / \
# /dev/discs/disc0/part1#/dev/discs/disc1/part1 \
# . \
# 1 2 0 swap - \
# /dev/discs/disc0/part5#/dev/discs/disc1/part5 \
# . \
# 0 2 0 ext3 /home \
# /dev/discs/disc0/part6#/dev/discs/disc1/part6 \
# .

# This makes partman automatically partition without confirmation.
d-i partman-md/confirm boolean true
d-i partman/confirm_write_new_label boolean true
d-i partman/choose_partition select finish
d-i partman/confirm boolean true

Base system installation

141.

There is actually not very much that can be preseeded for this stage of the installation. The only questions asked concern the installation of the kernel.

142.

# Select the initramfs generator used to generate the initrd for 2.6 kernels.
#d-i base-installer/kernel/linux/initramfs-generators string yaird

# The kernel image (meta) package to be installed; "none" can be used if no
# kernel is to be installed.
#d-i base-installer/kernel/image string linux-image-2.6-486
