Project Overview

systemcheck is a system health check tool for Kicksecure and Whonix. It runs a series of diagnostic functions and reports results via CLI and GUI (msgcollector).

Architecture

  • Shell scripts in usr/libexec/systemcheck/ with a .bsh file name extension are sourced by the main systemcheck script.
  • preparation.bsh's preparation function is run before any other checks, and provides shared helpers.
  • updatecheck is a related tool that checks for available package updates.
  • The canary system (including the canary-download Python script) fetches and verifies Kicksecure's warrant canary. It runs as user canary under AppArmor confinement.
  • log-checker is a standalone bash script invoked via leaprun (privilege escalation wrapper).
  • Configuration is sourced from /etc/systemcheck.d/*.conf and /usr/local/etc/systemcheck.d/*.conf.
