I am working on getting an unattended install iso setup for deploying the current LTS of Ubuntu (12.04.3) and have everything just the way I want it, except it is still asking for me to confirm the changes to the LVM. All my installs are on new VM's so there is nothing on the drives to be overwritten.

Here is the section of my preseed file for partitioning:

## 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.
# Alternatives: custom, some_device, some_device_crypto, some_device_lvm.
#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/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

# For LVM partitioning, you can select how much of the volume group to use
# for logical volumes.
d-i partman-auto-lvm/guided_size string max
#d-i partman-auto-lvm/guided_size string 10GB
#d-i partman-auto-lvm/guided_size string 50%

# 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{ }                \
#                      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{ }                \
#              .

# If you just want to change the default filesystem from ext3 to something
# else, you can do that without providing a full recipe.
#d-i partman/default_filesystem string ext4

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

## 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

Here are all the confirmation entries I have in my preseed (which uses LVM):

d-i partman/confirm_write_new_label     boolean true
d-i partman/choose_partition            select  finish
d-i partman/confirm_nooverwrite         boolean true
d-i partman/confirm                     boolean true
d-i partman-auto/purge_lvm_from_device  boolean true
d-i partman-lvm/device_remove_lvm       boolean true
d-i partman-lvm/confirm                 boolean true
d-i partman-lvm/confirm_nooverwrite     boolean true
d-i partman-auto-lvm/no_boot            boolean true
d-i partman-md/device_remove_md         boolean true
d-i partman-md/confirm                  boolean true
d-i partman-md/confirm_nooverwrite      boolean true

This should be more than what's needed for confirming all partitioning dialogs.

From the looks of what you have, you may be missing the d-i partman-md/confirm_nooverwrite boolean true or the d-i partman-md/confirm_nooverwrite boolean true entries (or both). Couldn't say in your case without you trying.

+1 I was also missing the "confirm_nooverwrite" settings, which this fixed. Thanks! –  David Gardner Jan 14 at 9:34
