APT-OSTree Project Todo

This file should only show things we are currently working on or still need to do. Completed blockes should be migrated into .notes/development_phases.md

This software is in alpha state. Assume things do not work even if they say they do. validate everything. Make sure actions (pkg install, etc) happen on their intended target. Not this host machine. If our logic in the apt-ostree code is incorrect, refer to .notes/inspiration/rpm-ostree-main to see how rpm-ostree did it. Update notes in .notes when appropriate as we make chnages. If we need to change the original rpm-ostree logic in apt-ostree due to environment, Fedora(DNF & rpm) vs debian(apt & dpkg), make note of it! But always try to to things the same way as rpm-ostree when possible.

🎯 Project Overview

APT-OSTree is a 1:1 CLI-compatible alternative to rpm-ostree using APT package management.

🚀 Next Steps

Real Environment Testing

  • Basic CLI Testing:
    • CLI compiles and runs successfully
    • Status command works (shows mock data)
    • List command works (shows real package data)
    • Search command works (searches APT database)
    • OCI commands available (build, push, pull, inspect, validate, convert) - Enhanced beyond rpm-ostree
    • rpm-ostree style OCI integration - compose build-chunked-oci, container-encapsulate, image
  • OSTree System Setup:
    • Test environment configuration
    • Bootloader integration
    • Deployment workflow testing
  • Integration Testing:
    • ✅ SUCCESS: bootc integration - Test compatibility with bootc container images
    • Native bootc on Ubuntu - Test with libostree 2025.2-1 (available in Ubuntu Questing)
    • fsverity integration - Test filesystem integrity verification
    • composefs integration - Test layered filesystem composition
  • Complete Application Testing:
    • Basic CLI commands working (status, list, search, install, upgrade)
    • OCI commands available (build, push, pull, inspect, validate, convert)
    • Compose commands available (tree, install, commit, image, etc.)
    • rpm-ostree style compose commands - build-chunked-oci, container-encapsulate, image (matches rpm-ostree exactly)
    • Start with clean OSTree environment (no packages)
    • Build up complete system using apt-ostree (similar to ublue's kionite)
    • Test full workflow: compose → deploy → package management → upgrades
    • Validate against rpm-ostree workflow for feature parity
  • End-to-End Testing:
    • Complete workflow validation
    • Error scenario testing
    • Performance benchmarking
