sp-variant

sp-variant - detect the Linux distribution for the StorPool build system

The sp-variant library is mainly useful within the StorPool internal build and QA environment, as well as the first step of installations on end-user systems. It examines several files and tries to determine what distribution and what version it is running on.

Basic command-line usage

• sp_variant detect - identify the current Linux distribution
• sp_variant show current - show JSON data about the current distribution
• sp_variant show all - show JSON data about all supported distributions
• sp_variant show NAME - show JSON data about a specific distribution
• sp_variant command list - show a list of distribution-specific commands
• sp_variant command run category.item [arg...] - run a distribution-specific command
• sp_variant repo add - add the Apt or Yum repository definitions for the StorPool package repository

Basic Python API

The sp_variant.variant module exports several constants and functions, among them:

• detect_variant() - return an object describing the detected distribution
• get_variant() - get an object describing the specified distribution
• get_by_alias() - same, but specify the StorPool builder alias for the distribution
• get_all_variants() - get objects describing all supported distributions
• command_run() - run a distribution-specific command

Basic Rust API

The sp-variant crate exports several constants and functions, among them:

• build_variants() - return information about all supported variants
• detect() - get an object describing the detected distribution
• get_from() - get an object describing the specified distribution
• get_by_alias_from() - same, but specify the StorPool builder alias for the distribution
