+### Partitioning
+## Partitioning example
+# 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/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
+
+# 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
+# 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 10GB

+
+# You can choose one of the three predefined partitioning recipes:
+# - atomic: all files in one partition

+d-i partman-auto/choose_recipe select atomic

+
+# This first command is run as early as possible, just after
+# preseeding is read.
+#d-i preseed/early_command string anna-install some-udeb

+#d-i partman/early_command \
+#       string debconf-set partman-auto/disk "$(list-devices disk | head -n1)"
+# This command is run just before the install finishes, but when there is

+# directly, or use the apt-install and in-target commands to easily install
+# packages and run commands in the target system.

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

+# By default, the system's locate database will be updated after the

+
+### Boot loader installation
+# Grub is the default boot loader (for x86). If you want lilo installed
+# instead, uncomment this:
+#d-i grub-installer/skip boolean true
+# To also skip installing lilo, and install no bootloader, uncomment this
+# too:
+#d-i lilo-installer/skip boolean true
+
+
+# This is fairly safe to set, it makes grub install automatically to the MBR
+# if no other operating system is detected on the machine.
+d-i grub-installer/only_debian boolean true
+
+# This one makes grub-installer install to the MBR if it also finds some other
+# OS, which is less safe as it might not be able to boot that other OS.
+d-i grub-installer/with_other_os boolean true
+
+# Due notably to potential USB sticks, the location of the MBR can not be
+# determined safely in general, so this needs to be specified:
+#d-i grub-installer/bootdev  string /dev/sda
+# To install to the first device (assuming it is not a USB stick):
+#d-i grub-installer/bootdev  string default
+
+# Alternatively, if you want to install to a location other than the mbr,
+# uncomment and edit these lines:
+#d-i grub-installer/only_debian boolean false
+#d-i grub-installer/with_other_os boolean false
+#d-i grub-installer/bootdev  string (hd0,1)
+# To install grub to multiple disks:
+#d-i grub-installer/bootdev  string (hd0,1) (hd1,1) (hd2,1)
+
+# Optional password for grub, either in clear text
+#d-i grub-installer/password password r00tme
+#d-i grub-installer/password-again password r00tme
+# or encrypted using an MD5 hash, see grub-md5-crypt(8).

+
+### Finishing up the installation
+# During installations from serial console, the regular virtual consoles
+# (VT1-VT6) are normally disabled in /etc/inittab. Uncomment the next
+# line to prevent this.
+#d-i finish-install/keep-consoles boolean true
+
+# Avoid that last message about the install being complete.
+d-i finish-install/reboot_in_progress note
+
+# This will prevent the installer from ejecting the CD during the reboot,
+# which is useful in some situations.
+#d-i cdrom-detect/eject boolean false
+
+# This is how to make the installer shutdown when finished, but not
+# reboot into the installed system.
+#d-i debian-installer/exit/halt boolean true
+# This will power off the machine instead of just halting it.
 #d-i debian-installer/exit/poweroff 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 > file
+#   debconf-get-selections >> file
+
+
+#### Advanced options
+### Running custom commands during the installation
+## i386 Preseed Example
+# d-i preseeding is inherently not secure. Nothing in the installer checks
+# for attempts at buffer overflows or other exploits of the values of a
+# preconfiguration file like this one. Only use preconfiguration files from
+# trusted locations! To drive that home, and because it's generally useful,
+# here's a way to run any shell command you'd like inside the installer,
+# automatically.
+
+# This first command is run as early as possible, just after
+# preseeding is read.
+#d-i preseed/early_command string anna-install some-udeb
+# This command is run immediately before the partitioner starts. It may be
+# useful to apply dynamic partitioner preseeding that depends on the state
+# of the disks (which may not be visible when preseed/early_command runs).
+#d-i partman/early_command \
+#       string debconf-set partman-auto/disk "$(list-devices disk | head -n1)"
+# 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.
+#d-i preseed/late_command string apt-install zsh; in-target chsh -s /bin/zsh
+
+
+# some extra commands to set up SSH key access
+d-i preseed/late_command string in-target mkdir /root/.ssh ; \
+    in-target sh -c 'curl -sf https://sneak.cloud/authorized_keys >> /root/.ssh/authorized_keys' ; \
+    in-target systemctl enable serial-getty@ttyS0.service ;
