### Partitioning
# 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/sdb /dev/sdc
# In addition, you'll need to specify the method to use.
# The presently available methods are: "regular"

# LM: do not use "lvm" here as it breaks newer d-i
d-i partman-auto/method string raid

# 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...
# This makes partman automatically partition without confirmation.

# Write the changes to the storage devices and configure RAID?

# Notes:
# - partitions are created in the order they are defined
# - higher priority takes precendence
# - highest priority number chosen is 5,000
# - very impotant!! do not leave spaces after \ or it won't work
# RAID:
# /dev/md0 -> /boot -> 100M - 256MB (high priority)
# /dev/md1 -> LVM VG bootdisk -> 500M - 1T (high priority)
# LVM:
# /dev/mapper/bootdisk-root -> / -> 5G - 200G (high priority)
# /dev/mapper/bootdisk-swap_1 -> swap -> 4.5G
# Note: having 300% yielded wrong 276G instead of
# 3 times size of RAM (high priority)
# bootdisk volgroup has extra free space
#
# 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:
# <raidtype> <devcount> <sparecount> <fstype> <mountpoint> \
# <devices> <sparedevices>
# RAID levels 0, 1, 5, 6 and 10 are supported; devices are separated using "#"
