A local build system for creating a customized Clonezilla Live ISO with additional packages and custom applications.

This project automates downloading, extracting, customizing, and repacking Clonezilla Live ISO images. It is intended for local builds on a Linux host using sudo and chroot.

Main build script. Performs the following steps:

1. Cleans previous rootfs
2. Downloads Clonezilla ISO
3. Extracts ISO and SquashFS
4. Customizes rootfs (installs packages, copies custom apps)
5. Repackages ISO
6. Produces final ISO in output/

Customizes the extracted rootfs:

• Mounts pseudo-filesystems (/dev, /proc, /sys, /dev/pts)
• Installs packages listed in config/packages.txt
• Copies custom applications from custom-apps/opt/
• Cleans up mounted pseudo-filesystems
• Uses chroot (requires sudo) for package installation

• Downloads the selected Clonezilla Live ISO to artifacts/clonezilla/
• Verifies SHA256 checksum
• Creates a symlink clonezilla-base.iso for consistent naming

• Extracts the downloaded ISO to artifacts/extracted/
• Extracts SquashFS filesystem into rootfs/

• Repackages the customized rootfs and ISO
• Supports both BIOS (isolinux) and UEFI (GRUB) boot
• Copies custom bootloader files from boot-files/

• Optional extra ISO customizations (e.g., boot menu modifications)
• Can be used to override default boot settings

• Helper scripts to manually enter or run commands inside the rootfs
• Useful for testing or debugging before repacking
• Both scripts use sudo chroot "$ROOTFS_DIR" environment

• setup-network.sh — optional networking setup inside rootfs
• update-boot-files.sh — updates bootloader files inside the ISO
• fix-scripts-format-to-utf8-lf.sh — normalizes line endings
• logging.sh — helper functions for standardized logging

• config/packages.txt — list of Debian/Ubuntu packages to install inside the rootfs.
  Example:

isc-dhcp-client
python3
curl

• custom-apps/opt/ — custom applications copied to /opt inside the rootfs.

• boot-files/ — custom EFI and isolinux boot files.

Run the main build script:

cd live-local-clonezilla
./build-scripts/build-local.sh

• You will be prompted for your sudo password.
• The script handles mounting, chroot, package installation, and cleanup automatically.
• Packages listed in config/packages.txt will be installed in the rootfs.

• Final ISO is located in: output/hardclone/
• ISO filename format: hardclone-clonezilla-live-<version>-<timestamp>.iso
• ISO label format: HC-Clonezilla-<version>
