+### Network configuration
+d-i netcfg/enable boolean true

+# it, this might be useful.
+d-i netcfg/dhcp_timeout string 60
+
+# 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.
+d-i netcfg/dhcp_failed note

+# Any hostname and domain names assigned from dhcp take precedence over

+# from being shown, even if values come from dhcp.

+## Partitioning example
+# Specify a disk to partition.
+# For example, to use the first SCSI/SATA hard disk:
+d-i partman-auto/disk string /dev/{{ boot_disk_name }}
+# 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
+
+# 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
+

+d-i partman-lvm/confirm_nooverwrite boolean true
+
+# 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
+
+# This makes partman automatically partition without confirmation, provided
+# that you told it what to do using one of the methods above.

+### Boot loader installation
+# Grub is the boot loader (for x86).

+# This is fairly safe to set, it makes grub install automatically to the UEFI
+# partition/boot record if no other operating system is detected on the machine.
+d-i grub-installer/only_debian boolean true

+### 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 > /target/root/preceed.cfg
+   debconf-get-selections >> /target/root/preceed.cfg
+
+# This command is run just before the install finishes, but when there is
+# still a usable /target directory. You can chroot to /target and use it
+# directly, or use the apt-install and in-target commands to easily install
+# packages and run commands in the target system.
