Hence, Chrooting consist in Changing the root Directory to a Different Partition from the Boot System.

And Chroot is also defined as the Operation that Changes the Apparent root Directory for the Current Running Process and their Children.

Here are some Key Aspects of the chroot Command:

  • Isolation: One of the primary purposes of chroot is to create a sandbox environment where processes are confined to a specific directory subtree. This isolation helps prevent access to files and directories outside the specified root, enhancing security and preventing accidental damage to the system.
  • System Maintenance and Recovery: chroot is commonly used during system maintenance and recovery operations, such as repairing a broken system or reinstalling the operating system. By changing the root directory to a mounted filesystem containing the necessary tools and utilities, administrators can perform repairs and operations without affecting the rest of the system.
  • Testing and Development: Developers and testers often use chroot to create isolated environments for testing software or developing new features. By setting up a chroot environment with specific libraries, dependencies, and configurations, they can ensure that software behaves consistently across different systems and configurations.
  • Virtualization and Containerization: While chroot provides basic filesystem isolation, it is not a full-fledged virtualization or containerization solution like Docker or virtual machines. However, chroot can be a building block for implementing more advanced virtualization and containerization techniques by combining it with other tools and technologies.
  • Security Considerations: Despite its usefulness, chroot has limitations and may not provide complete security isolation. It does not isolate processes at the kernel level, so it may not be sufficient for securing sensitive or untrusted applications. Users should be aware of its limitations and use additional security measures as needed.

Especially relevant: the Chroot is usually achieved Starting up the System with a Live OS Media.

As a Result you’ll be able to Operate on the New Root Device pretty like a regularly Started System with Networking.
