pyplugins.interventions.kernelversion module

Kernel Version Utilities

This module provides utilities for parsing, comparing, and representing Linux kernel version strings. It is intended to help plugins and scripts that need to reason about kernel versions in the Penguin framework or similar environments.

Features

• Parse kernel version strings into structured objects

• Compare kernel versions for ordering and equality

• Convert kernel version objects back to string representation

Classes

• KernelVersion: Represents a parsed kernel version and supports comparison.

class pyplugins.interventions.kernelversion.KernelVersion

Bases: Plugin

Represents a Linux kernel version and supports comparison operations.

Attributes - outdir (Optional[str]): Output directory. - sysname (Optional[str]): System name. - nodename (Optional[str]): Node name. - release (Optional[str]): Kernel release string. - version (Optional[str]): Kernel version string. - machine (Optional[str]): Machine architecture. - domainname (Optional[str]): Domain name.

Example `python v = KernelVersion(5, 10, 0, "-rc1") `
