-# Live Exam OS Builder
-
-This project builds a customized ISO image used during live exam with nexus. The following features are supported: root filesystem encryption, PXE booting, secure boot, OS and filesystem configuration.
-
-## Usage
-
-A Makefile is provided to build the nexus live exam ISO image. This Makefile takes care of running the build script, `build.sh`, inside a container in order to avoid any potential corruption of the host system. Indeed, the script binds directories such as `/dev`, `/sys`, etc. to the created filesystem. If a problem occurs during this process, the host system might be affected and possibly corrupted.
-
-Consequently, make absolutely sure to NOT DIRECTLY RUN `build.sh` on the host system! Instead, use `make` as described below:
-
-1. First, prepare the container image required by the build process:
- ```bash
- make prepare
- ```
-
-2. Then, run the ISO image build process with the desired config:
- ```bash
- make build conf=<env>
- ```
- Where `<env>` is the path to a file containing the config to use when building the image. The config is specified through environment variables described in the next section.
-
-## Configuration
-
-Here is a sample configuration file listing all supported variables. In this example, encryption is disabled. To activate it, uncomment the block under `[Encryption settings]`.
-
-```bash
-# [General settings]
-# Final ISO image to produce
-export ISO_NAME="nexus.iso"
-# Whether to produce extra messages
-export VERBOSE=true
-# Output directory for generated files
-export OUTPUT="output"
-# Directory where to download packages for the initial root filesystem
-export CACHE_FS="cache"
-
-# [nexus-exam settings]
-# nexus server ip and port
-export SERVER="127.0.0.1:1077"
-# Path, within the current directory, to the public certificate file used by nexus-exam
-export CERT="ca-cert.pem"
-# Default user for nexus-exam
-export EXAM_USER='luke@force.net'
-# Default password for nexus-exam
-export EXAM_PWD='r2d2'
-
-# [Encryption settings]
-# Enable LUKS encryption with passphrase
-# export LUKS_PASSPHRASE='passphrase'
-# List of additional keys
-# export ADDITIONAL_KEYS='key1 key2'
-# Copy the rootfs to RAM (instead of being stored on the usb key)
-#export RAM="squashfs_tmpfs"
-
-# [PXE settings]
-# Set the url of the PXE server and generate an initramfs, kernel and squashfs for PXE to use
-# Use the url of the directory where squashfs is stored, not the direct link to it
-#export PXE_URL="127.0.0.1:8000"
-```
-
-## Makefile Targets
-
-The default target is `help`, which shows the available targets:
-
-```
-$ make
-Available targets:
-prepare Prepare the container image used by the build script
-build Build the ISO image by running the build script inside a container
- require the conf variable which specifies the config file to use, e.g.
- make build conf=my_awsome_env
-bios Boot the ISO as a harddisk in legacy mode (BIOS)
-bios_cd Boot the ISO on a CD-ROM in legacy mode (BIOS)
-uefi Boot the ISO as a harddisk in UEFI mode
-```
-
-Note that a QEMU virtual machine is used when booting the ISO image.
-
-## Project Components
-
-### Scripts
-
- - **build.sh**: Main script to build the ISO image and configure the environment.
- - **tools/functions.sh**: Contains helper functions used by the build.sh script to streamline operations and ensure consistency.
-
-### Configuration Files
-
-The configuration files are organized in the `config/` directory and include the following subdirectories:
-
-- **config/00-bootloader**: Contains bootloader configuration files.
- - grub.cfg, grub.efi.cfg, limine.conf
-
-- **config/01-packages_install**: Lists packages to be installed.
- - packages
-
-- **config/02-customisation**: Contains customization files for the filesystem.
- - etc/, home/, usr/
-
-- **config/03-post_install**: Contains post-installation scripts to further customize the environment.
- - 1000-create-user.sh, 2000-enable_services.sh, 3000-nexus_exam.sh, 5000-push_challenge.sh, 8000-initramfs.sh, 1000-disable_root.sh, 2500-disable_services.sh, 4000-firewall.sh, 5000-pxe.sh, 9999-cleanup.sh
-
-### Wifi Connection
-
-Each wifi connection must reside in a `.nmconnection` file located in `config/02-customisation/etc/NetworkManager/system-connections/`.
-
-Here are two example files, `wifi1.nmconnection` and `wifi2.nmconnection`. Make sure that whatever configuration files you copy in that directory **cannot be read by anyone**, but root:
-```
-chmod 600 config/02-customisation/etc/NetworkManager/system-connections/*.nmconnection
-```
-
-Content of `wifi1.nmconnection`:
-```
-[connection]
-# Name of the connection as shown by Network Manager
-id=example1
-# Random UUID referencing the connection
-uuid=8a065b14-beb3-4f28-97b5-f560c368ae12
-type=wifi
-
-[wifi]
-# Whether the SSID is hidden or not (true/false)
-hidden=false
-# Name of the WIFI SSID
-ssid=the_empire_strickes_back
-
-[wifi-security]
-key-mgmt=wpa-eap
-
-[802-1x]
-eap=peap;
-identity=luke_skywalker
-password=you_are_not_ready_young_padawan
-phase2-auth=mschapv2
-
-[ipv4]
-method=auto
-
-[ipv6]
-addr-gen-mode=stable-privacy
-method=auto
-```
-
-Content of `wifi2.nmconnection`:
-```
-[connection]
-# Name of the connection as shown by Network Manager
-id=example2
-# Random UUID referencing the connection
-uuid=8a065b14-beb3-4f28-97b5-f560c368ae12
-type=wifi
-
-[wifi]
-# Whether the SSID is hidden or not (true/false)
-hidden=true
-# Name of the WIFI SSID
-ssid=return_of_the_jedi
-mode=infrastructure
-
-[wifi-security]
-auth-alg=open
-key-mgmt=wpa-psk
-psk=may_the_force_be_with_you
-
-[ipv4]
-method=auto
-
-[ipv6]
-addr-gen-mode=stable-privacy
-method=auto
-```
-## Notes
-
-- Ensure that all required dependencies are installed before running the script or Makefile.
-- For UEFI testing, verify that the OVMF firmware is installed on your system (e.g., `/usr/share/OVMF/x64/OVMF.fd`).
-- When specifying a cache directory or a directory for downloading the filesystem, avoid using `/tmp` in the container, as it is often set with the noexec attribute, which can prevent tools like debootstrap from working properly. Choose a directory with execution permissions instead.
