Quick Start

Install

Packages are built automatically for every supported family. Download the latest from GitHub Releases or add the official repository:

sudo coa tools repo add

From source

git clone https://github.com/pieroproietti/penguins-eggs.git
cd penguins-eggs
make
sudo make install

Requirements: gcc, make, golang 1.25+, git.

Your first ISO in three commands

# 1. Prepare the system (install squashfs-tools, xorriso, etc.)
sudo coa tools repo add

# 2. Remaster the running system into a live ISO
sudo coa remaster

# 3. Find your ISO
ls /home/eggs/*.iso

That's it. The ISO is hybrid (BIOS + UEFI) and ready to boot from USB or in a VM.

Common workflows

Customize the desktop, then remaster

# Apply a preset desktop configuration ("costume")
coa wardrobe get
coa wardrobe list
sudo coa wardrobe wear colibri

# Build the ISO
sudo coa remaster

Customize compression and ISO naming

# Open the interactive configuration TUI
sudo coa config

Change the live user password, the compression algorithm (zstd/xz/lz4/gzip), the compression level, the ISO filename prefix, and edit the custom exclude list — all from a single interface. Settings are saved to /etc/penguins-eggs.d/custom.yaml and applied automatically on the next coa remaster.

Remaster with LUKS encryption (Debian family)

sudo coa remaster --crypted

An interactive TUI lets you choose the passphrase and crypto parameters. The resulting ISO boots into a LUKS-encrypted live environment.

Install to disk from the live ISO

# GUI (requires Calamares and a display server)
sudo coa sysinstall calamares

# TUI (works on console, serial, ssh)
sudo coa sysinstall krill

# Headless / unattended
sudo coa sysinstall krill --unattended

Debug a remaster problem

# Stop after a specific step, leaving the chroot mounted for inspection
sudo coa remaster --stop-after coa-initrd

# Print the JSON flight plan without building anything
sudo coa remaster --debug

# Clean up after a failed or interrupted remaster
sudo coa destroy

Boot an ISO from the hard drive (no USB needed)

# Generate a GRUB loopback entry for any Linux ISO
coa tools grub40 /path/to/my.iso

# Write it directly into /etc/grub.d/40_custom
sudo coa tools grub40 /path/to/my.iso --write
sudo update-grub
