Introduction to VSO (with examples)

1: Check for system updates to the host system

Code:

vso sys-upgrade check

Motivation: Checking for system updates is important to ensure that the host system is up to date with the latest security patches and software improvements. By running this command, you can easily determine whether any updates are available for your system.

Explanation: The sys-upgrade check command is used to check for system updates to the host system. It queries the package manager to determine if any software updates are available.

Example Output:

Checking for system updates...
No updates available.

2: Upgrade the host system now

Code:

vso sys-upgrade upgrade --now

Motivation: Regularly upgrading the host system is crucial to benefit from the latest features, bug fixes, and security updates. Running this command allows you to upgrade the host system immediately.

Explanation: The sys-upgrade upgrade --now command upgrades the host system. The --now option ensures that the upgrade process is initiated immediately, without any user intervention.

Example Output:

Upgrading the host system...
System upgrade completed successfully.

3: Initialize the Pico subsystem

Code:

vso pico-init

Motivation: Initializing the Pico subsystem is necessary before performing any operations related to package management. This command sets up the necessary environment for managing packages inside the Pico subsystem.

Explanation: The pico-init command initializes the Pico subsystem. It creates the necessary directories, config files, and sets up the package manager to work within the Pico subsystem.

Example Output:

Initializing Pico subsystem...
Pico subsystem successfully initialized.

4: Install applications inside the subsystem

Code:

vso install package1 package2 ...

Motivation: Installing applications within the subsystem provides isolation and separation from the host system. It allows for easy installation and management of software packages specifically for the subsystem.

Explanation: The install command is used to install applications inside the subsystem. Simply provide the package names that you want to install as arguments to the command.

Example Output:

Installing package1...
Package1 installation complete.

Installing package2...
Package2 installation complete.

5: Remove applications from the subsystem

Code:

vso remove package1 package2 ...

Motivation: Removing applications from the subsystem helps to keep your system clean and organized. If you no longer need certain packages within the subsystem, running this command allows you to easily remove them.

Explanation: The remove command is used to remove applications from the subsystem. Specify the package names that you want to remove as arguments to the command.

Example Output:

Removing package1...
Package1 removal complete.

Removing package2...
Package2 removal complete.

6: Enter the subsystem’s shell

Code:

vso shell

Motivation: Entering the subsystem’s shell provides a command-line interface specifically for managing packages and running applications within the subsystem. This allows for a more focused and streamlined workflow.

Explanation: The shell command is used to enter the subsystem’s shell. Once inside, you can execute commands and interact with the package manager and applications installed within the subsystem.

Example Output:

Entering the subsystem's shell...

Pico Shell Version X.X.X
...

(subsystem)$

7: Run an application from the subsystem

Code:

vso run package

Motivation: Running an application from the subsystem allows you to utilize the software packages installed within the subsystem without affecting the host system. This is particularly useful when you want to use a specific version of a package or test an application in an isolated environment.

Explanation: The run command is used to execute an application from the subsystem. Specify the package name of the application that you want to run as an argument to the command.

Example Output:

Running package...
Application started successfully.

8: Display VSO configuration

Code:

vso config show

Motivation: Viewing the VSO configuration helps in understanding the current settings and options used by the system. This allows for easier troubleshooting and customization of the VSO environment.

Explanation: The config show command is used to display the VSO configuration. It provides information about the current settings, such as package manager details, package repository URLs, and other relevant system parameters.

Example Output:

Displaying VSO configuration...

Package Manager: Pico Package Manager
Repository URL: https://packages.example.com
...

Configuration options:
...
