Chroot allows user based namespace isolation on many standard Linux deployments.

## 1. Prerequisites

- Familiarity with [chroot](http://man7.org/linux/man-pages/man2/chroot.2.html)
- Chroot installed on your machine.

## 2. Install MinIO in Chroot

즉, 파이썬에서 환경 변수로부터 읽은 **모든 값**은 **`str`**이 되고, 다른 타입으로의 변환이나 검증은 코드에서 수행해야 합니다.

**애플리케이션 설정**을 처리하기 위한 환경 변수 사용에 대한 자세한 내용은 [고급 사용자 가이드 - 설정 및 환경 변수](./advanced/settings.md) 에서 확인할 수 있습니다.

## `PATH` 환경 변수 { #path-environment-variable }

**`PATH`**라고 불리는, **특별한** 환경변수가 있습니다. 운영체제(Linux, macOS, Windows)에서 실행할 프로그램을 찾기위해 사용됩니다.

///

Активація віртуального середовища додає його шлях `.venv/bin` (на Linux і macOS) або `.venv\Scripts` (на Windows) до змінної оточення `PATH`.

Скажімо, до активації середовища змінна `PATH` виглядала так:

//// tab | Linux, macOS

```plaintext
/usr/bin:/bin:/usr/sbin:/sbin
```

Це означає, що система шукатиме програми в:

* `/usr/bin`

To run the standard library tests, enable Cgo and use an appropriate
C compiler from the Android NDK. For example,

	CGO_ENABLED=1 \
	GOOS=android \
	GOARCH=arm64 \
	CC_FOR_TARGET=$NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android21-clang \
	./all.bash

To run tests on the Android device, add the bin directory to PATH so the
go tool can find the go_android_$GOARCH_exec wrapper generated by

       * Refer [windows setup guide](https://www.tensorflow.org/install/gpu#windows_setup).
     * If you have above configuration and using _**Ubuntu/Linux**_ platform -
       * Try adding the CUDA, CUPTI, and cuDNN installation directories to the $LD_LIBRARY_PATH environment variable.
       * Refer [linux setup guide](https://www.tensorflow.org/install/gpu#linux_setup).

これらの環境変数が扱えるのは**テキスト文字列**のみです。環境変数はPythonの外部にあり、他のプログラムやシステム全体（Linux、Windows、macOSなど異なるオペレーティングシステム間も）との互換性が必要になるためです。

つまり、環境変数からPythonで読み取る**あらゆる値**は **`str`になり**、他の型への変換やバリデーションはコード内で行う必要があります。

環境変数を使って**アプリケーション設定**を扱う方法については、[高度なユーザーガイド - Settings and Environment Variables](./advanced/settings.md)で詳しく学べます。

## `PATH`環境変数 { #path-environment-variable }

**`PATH`**という**特別な**環境変数があります。これはオペレーティングシステム（Linux、macOS、Windows）が実行するプログラムを見つけるために使用されます。
