#d-i netcfg/get_hostname string your-PC-name
#d-i netcfg/get_domain string 

# If non-free firmware is needed for the network or other hardware, you can

# NTP server to use. The default is almost always fine here.
d-i clock-setup/ntp-server string ntp.nict.jp

### Partitioning
## Partitioning example

# 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

# 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
#d-i partman-auto/disk string /dev/nvme0n1
# In addition, you'll need to specify the method to use.
#d-i partman-auto/init_automatically_partition select Guided - use entire disk
# 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
d-i     partman-auto/method string regular
#LVMは使わない
d-i     partman-lvm/confirm boolean false
# 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

# 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

# Set the default filesystem
d-i partman/default_filesystem string ext4

# Install without swap space
d-i partman-basicfilesystems/no_swap boolean false

# This makes partman automatically partition without confirmation, provided
# that you told it what to do using one of the methods above.
d-i partman-partitioning/confirm_write_new_label boolean true
d-i partman/choose_partition select Finish partitioning and write changes to disk
d-i partman/confirm boolean true 
d-i partman/confirm_nooverwrite boolean true
d-i partman-md/confirm boolean true
