# Debian archive security string
security-string: "security.debian.org"
# Debian has the following services that provide updates.
#
# Security updates help to keep your system secured against attacks.
# Enabling this service is strongly recommended.
#
# Release updates provide more current versions for software that changes relatively
# frequently and where not having the latest version could reduce the usability of the
# software. It also provides regression fixes. This service is only available for stable
# and oldstable releases.
#
# Backported software is adapted from the development version to work with this release.
# Although this software has not gone through such complete testings as that contained in
# the release, it includes newer versions of some applications that may provide useful
# features. Enabling backports here does not cause any of them to be installed by default;
# it only allows you to manually select backports to use.
updates:
backports: true
release: true
security: true
# Applying updates on a frequent basis is an important part of keeping the system secure.
#
# By default, security updates are not automatically installed, as security advisories should be
# reviewed before manual installation of the updates using standard package management tools.
#
# Alternatively, the unattended-upgrades package can be installed, which will install security
# updates automatically.
# Note, however, that automatic installation of updates may occasionally cause unexpected downtime
# of services provided by this machine in the rare cases where the update is not fully backward-compatible,
# or where the security advisory requires the administrator to perform some other manual operation.
#
# Possible choices: none, security, unattended (RECOMMENDED)

# Please specify the architecture of the server to be installed:
arch: "amd64" # MUST be "amd64" || "intel64". "arm64" is NOT supported
# This is how to make the installer shutdown when finished, but not reboot:
exit-halt: false
# This will power off the machine instead of just halting it (RECOMMENDED):
exit-poweroff: true
# This will reboot the machine:
exit-reboot: false
# If non-free firmware is needed for the network or other hardware, you can configure the #
# installer to always try to load it without prompting.
firmware-install: true
# Firmware settings
# "never": Completely disables the firmware search.
# "missing": Searches only when the firmware is needed. (default)
# "always": Always searches and asks for any firmware that could be useful for the hardware.

kernel: "linux-image-6.12.12+bpo-amd64"
###########################################################################################
# GRUB2 settings #
###########################################################################################
grub:
background:
# If you want to change the GRUB background, please change to "true":
enable: true
# Specify the path from which the image should be loaded.
# RECOMMENDED settings: JPG 1280 x 1024 px or JPG 1920 x 1080 px
path: "/root/CISS.2025.debian.installer/.assets/background/background_hexagon_1280.jpg"
# Due notably to potential USB sticks, the location of the primary drive cannot be
# determined safely in general, so this needs to be specified:
bootdev: "/dev/sda"
# Force GRUB installation to the EFI removable media path?
# It seems that this computer is configured to boot via EFI, but maybe that configuration will
# not work for booting from the hard drive. Some EFI firmware implementations do not meet the
# EFI specification (i.e., they are buggy) and do not support proper configuration of boot
# options from system hard drives.
#
# A workaround for this problem is to install an extra copy of the EFI version of the GRUB
# bootloader to a fallback location, the "removable media path". Almost all EFI systems, no
# matter how buggy, will boot GRUB that way.
#
# Warning: If the installer failed to detect another operating system that is present on your
# computer that also depends on this fallback, installing GRUB there will make that operating
# system temporarily unbootable. GRUB can be manually configured later to boot it if necessary:
force-efi-extra-removable: false
# Set this to 'true' to install the latest GRUB2 backported package for encrypted '/boot' support.
# MUST be 'true' in the case of 'LUKS2' and / or 'dm-integrity' encrypted '/boot/':
latest: true
# 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:
only-debian: true
# This one makes grub-installer install to the UEFI partition/boot record, if it also finds
# some other OS, which is less safe as it might not be able to boot that other OS:
other-os: true
# OS-prober did not detect any other operating systems on your computer at this time, but you
# may still wish to enable it in case you install more in the future:
prober: false
# Skip installing grub:
skip: false
# Update NVRAM variables to automatically boot into Debian?
# GRUB can configure your platform's NVRAM variables so that it boots into Debian automatically
# when powered on. However, you may prefer to disable this behavior and avoid changes to your
# boot configuration. For example, if your NVRAM variables have been set up such that your
# system contacts a PXE server on every boot, this would preserve that behavior:
update-nvram: true
