bootc Development Report

Project: Debian Atomic (Fedora Atomic 1:1 Parallel)
Report Date: 2025-08-17

📋 Executive Summary

bootc is the primary tool for managing bootable container images in Debian Atomic, serving as the equivalent of Fedora Atomic's bootc. The tool is fully functional for basic operations but has configuration issues preventing live installation on Debian systems. This report documents the current status, testing results, and specific issues requiring attention.

🚧 Critical Issues Found

1. OSTree Reference Creation Issue (BLOCKING)

Severity: Critical
Description: OSTree commits are created but references are not accessible
Error Message: No commit objects found
Impact: Prevents live installation on Debian systems
Status: Blocking live installation testing

Technical Details

  • ✅ OSTree Commits: Successfully created with commit hashes
  • ❌ OSTree References: Not created in accessible format
  • ❌ bootc Access: Cannot find commits without proper refs
  • 🔄 Progress: Resolved configuration path issue, now blocked by ref creation

Current Workaround

  • Components tested manually in existing Debian environment
  • Live installation testing blocked until ref issue resolved

2. OSTree Configuration Path Issue (RESOLVED)

Severity: Resolved
Description: bootc install could not find ostree/prepare-root.conf
Status: ✅ RESOLVED - Multiple configuration file locations implemented
Solution: Configuration files placed in /usr/lib/ostree/, /etc/ostree/, and /usr/share/ostree/
