## B.4.1. Localization

# Preseeding only locale sets language, country and locale.
d-i debian-installer/locale string en_US

# The values can also be preseeded individually for greater flexibility.
#d-i debian-installer/language string en
#d-i debian-installer/country string NL

# Optionally specify additional locales to be generated.

# To select a variant of the selected layout (if you leave this out, the
# basic form of the layout will be used):
#d-i keyboard-configuration/variantcode string dvorak

## B.4.2. Network configuration

# Disable network configuration entirely. This is useful for cdrom
# installations on non-networked devices where the network questions,
# warning and long timeouts are a nuisance.
#d-i netcfg/enable boolean false

# netcfg will choose an interface that has link if possible. This makes it
# skip displaying a list if there is more than one interface.
#d-i netcfg/choose_interface select auto

# To pick a particular interface instead:
#d-i netcfg/choose_interface select eth1

# If you have a slow dhcp server and the installer times out waiting for
# it, this might be useful.

# If you prefer to configure the network manually, uncomment this line and
# the static network configuration below.
#d-i netcfg/disable_autoconfig boolean true

# If you want the preconfiguration file to work on systems both with and
# without a dhcp server, uncomment these lines and the static network
# configuration below.

## B.4.3. Network console

# Use the following settings if you wish to make use of the network-console
# component for remote installation over SSH. This only makes sense if you
# intend to perform the remainder of the installation manually.
#d-i anna/choose_modules string network-console
#d-i network-console/password password abc123
#d-i network-console/password-again password abc123
# Use this instead if you prefer to use key-based authentication
#d-i network-console/authorized_keys_url http://host/authorized_keys

## B.4.4. Mirror settings

# If you select ftp, the mirror/country string does not need to be set.

# ALTERNATIVE: ubuntu ports, CPUs of aarch64 and so on.
#d-i apt-setup/security_path string /ubuntu-ports/

# Alternatively: by default, the installer uses CC.archive.ubuntu.com where
# CC is the ISO-3166-2 code for the selected country. You can preseed this
# so that it does so without asking.
#d-i mirror/country string CN
#d-i mirror/http/mirror select cn.archive.ubuntu.com

## B.4.5. Clock and time zone setup

# Controls whether or not the hardware clock is set to UTC.
#d-i clock-setup/utc boolean false
d-i clock-setup/utc boolean false

# You may set this to any valid setting for $TZ; see the contents of

# Controls whether to use NTP to set the clock during the install
#d-i clock-setup/ntp boolean false
d-i clock-setup/ntp boolean false
# NTP server to use. The default is almost always fine here.
#d-i clock-setup/ntp-server string ntp.example.com

## B.4.6. 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.
# 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

d-i partman-lvm/confirm_nooverwrite boolean true
# 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
# Name of the volume group for the new system:
d-i partman-auto-lvm/new_vg_name	string	vg
# And the same goes for the confirmation to write the lvm partitions.
d-i partman-lvm/confirm boolean true
# 没有 swap 分区, 是否返回修改分区?
d-i partman-basicfilesystems/no_swap boolean false

# 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 home

# 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:

## B.4.14. Preseeding other packages

# Depending on what software you choose to install, or if things go wrong
# during the installation process, it's possible that other questions may
# be asked. You can preseed those too, of course. To get a list of every
# possible question that could be asked during an install, do an
# installation, and then run these commands:
#   debconf-get-selections --installer > file
#   debconf-get-selections >> file
