Debian preseed configuration

#### Contents of the preconfiguration file
### Localization
# Preseeding only locale sets language, country and locale.
d-i debian-installer/locale string fr_FR

# Keyboard selection.
d-i keyboard-configuration/layoutcode string fr
d-i keyboard-configuration/variantcode select
# To select a variant of the selected layout:
d-i keyboard-configuration/xkb-keymap select fr

### Network configuration
# 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

# Any hostname and domain names assigned from dhcp take precedence over
# values set here. However, setting the values still prevents the questions
# from being shown, even if values come from dhcp.
d-i netcfg/get_hostname string localhost
d-i netcfg/get_domain string localhost

{% if proxy_env is defined %}
### Mirror settings
# Set proxy
d-i mirror/http/proxy string {{ proxy_env['http_proxy'] }}
{% endif %}

# 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/http/mirror select fr.archive.ubuntu.com

### Account setup
# To create a normal user account.
d-i passwd/user-fullname string admin
d-i passwd/username string admin
# Normal user's password, either in clear text
#d-i passwd/user-password password user
#d-i passwd/user-password-again password user
# or encrypted using a crypt(3) hash.
d-i passwd/user-password-crypted password {{ encrypted_password }}

# Set to true if you want to encrypt the first user's home directory.
d-i user-setup/encrypt-home boolean false

### Clock and time zone setup
# Controls whether or not the hardware clock is set to UTC.
d-i clock-setup/utc boolean true

# You may set this to any valid setting for $TZ; see the contents of
# /usr/share/zoneinfo/ for valid values.
d-i time/zone string Europe/Paris

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

### Partitioning

# use LVM to partition the disk
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

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

# 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
#TODO d-i partman-auto/choose_recipe select boot-root

### Package selection

d-i ubiquity/success_command string in-target apt -y install openssh-server

# Some versions of the installer can report back on what software you have

# popular and include it on CDs.
