Overview

PandaOS is a minimal Linux-based operating system. It provides a basic shell environment for experimentation and learning. It's my kinda hobby project, just experimenting - nothing serious. [MOON]

Project Structure

PandaOS/
├── kernel/          # TinyCore Linux kernel (vmlinuz)
├── rootfs/          # Root filesystem structure
│   └── init        # Init script
├── boot/            # Bootloader configuration
│   └── grub/       # GRUB configuration
├── iso/             # Build output directory
└── build.sh         # Build scrip

Requirements

To build PandaOS, you'll need:

• bash
• grub-mkrescue or xorriso (for creating ISO)
• cpio and gzip (for initramfs)
• busybox (recommended, for basic utilities)

On Fedora/RHEL:

sudo dnf install grub2-tools xorriso cpio gzip busybox

Building

1. Make the build script executable:

chmod +x build.sh

2. Run the build script:

./build.sh

This will create a bootable ISO image named pandaos-YYYYMMDD.iso in the project root.

Booting

You can boot the ISO using:

• QEMU/KVM:

qemu-system-x86_64 -cdrom pandaos-YYYYMMDD.iso -m 512M

• VirtualBox/VMware: Create a new VM and boot from the ISO

Features

• 🐼 Custom ASCII Art - Beautiful panda art on boot
• 🛠️ Minimal Init System - Lightweight and fast
• 💻 Basic Shell Environment - BusyBox-based shell with essential utilities
• 📝 Nano Text Editor - Full-featured text editor included
• 📊 Fastfetch - System information display tool
• 🔧 Mounted Filesystems - proc, sys, and dev filesystems ready
• 📁 Writable Directories - /root and /tmp for file operations

Customization

• Edit rootfs/init to customize the boot process
• Modify boot/grub/grub.cfg to change boot options
• Add more utilities to the initramfs in build.sh
• Replace kernel/vmlinuz with any Linux kernel
