debootstrap: Create an Ubuntu 20.04 system inside the `focal-root` directory with a local mirror.

try on your machine

The command "sudo debootstrap focal ${path-to-focal-root-} ${file:---path-to-mirror-}" is used to bootstrap a basic Ubuntu system using the "debootstrap" tool.

Here's a breakdown of each component of the command:

"sudo": It is a command that allows you to execute the following command with administrative privileges. Admin privileges are often required to perform system-level operations.
"debootstrap": It is a tool commonly used in Debian-based systems, including Ubuntu, to install a minimal system into a subdirectory. It sets up the basic directory structure and installs the necessary packages to create a functional system.
"focal": It specifies the release name or version of Ubuntu that you want to bootstrap. In this case, it is "focal," which refers to Ubuntu 20.04 LTS (Long Term Support) release.
"${path-to-focal-root-}": It represents the path where the bootstrap process will create the new Ubuntu system. You need to provide the actual path to the desired directory.
"${file:---path-to-mirror-}": It specifies the mirror or package repository to be used during the bootstrap process. You need to provide the actual path to the apt-mirror configuration file or can directly specify the URL of the repository.

By executing this command, you will initiate the debootstrap process for creating a basic Ubuntu system in the specified directory, using the provided Ubuntu version and mirror repository.
