## README

This project aims to provide a convenient set of tools for creating and managing root filesystem (rootfs) images based on Ubuntu. Key features include mounting system directories, entering a chroot environment, and cleaning up dependencies. Below is a brief guide on using this project.

## Features

- **Permission Check**: Ensures the script runs with root privileges.
- **Directory Validation**: Verifies that the target directory exists and is valid.
- **System Directory Mounting**: Automatically mounts essential system directories such as proc, sys, etc.
- **Chroot Environment Access**: Provides functionality to enter the newly built rootfs environment.
- **Dependency Check**: Verifies that required packages are installed before execution.
- **Colored Output**: Uses color coding to distinguish different types of information for easier readability.

## Installation and Configuration

1. Clone the repository to your local machine:
   ```bash
   git clone https://gitee.com/solomon2020/make_ubuntu_rootfs.git
   ```

2. Navigate to the project directory:
   ```bash
   cd make_ubuntu_rootfs
   ```

## Usage Instructions

### Prerequisites

- Ensure you have downloaded the Ubuntu base tarball and placed it in the correct directory, such as `ubuntu-22.04.5-base` or `ubuntu-24.04-base`.

### Running the Scripts

#### mnt_chroot.sh

This script mounts system directories and enters the chroot environment.

```bash
sudo ./mnt_chroot.sh /path/to/your/rootfs
```

#### mkRootfsimg.sh

This script creates a rootfs image.

```bash
sudo ./mkRootfsimg.sh
```

## Cleanup

To clean up temporary files and unmount system directories, use the following command:

```bash
sudo ./mnt_chroot.sh -u /path/to/your/rootfs
```
