Next Steps After Go Installation - deb-bootc-image-builder

Date: August 17, 2025
Status: 🚧 Ready for Binary Recompilation - All Fixes Implemented

---

🎯 Overview

This document outlines the exact steps to take once Go 1.21+ is installed on the development system. All critical fixes have been implemented in the source code, and the testing strategy is complete. The only remaining blocker is binary recompilation to activate these fixes.

---

🔧 Step 1: Install Go 1.21+

Installation Commands

# Update package lists
sudo apt update

# Install Go 1.21+
sudo apt install -y golang-go

# Verify installation
go version

# Check Go version (should be 1.21 or higher)
go version | grep -o "go[0-9]\+\.[0-9]\+"

Verification

# Should show Go 1.21+ version
go version

# Should show Go binary location
which go

# Should show Go environment
go env GOPATH GOROOT

---

🔨 Step 2: Recompile Binary with Sudo Fixes

Compilation Commands

# Navigate to project directory
cd /opt/Projects/deb-bootc-image-builder

# Navigate to bib directory
cd bib

# Build new binary with all fixes
go build -o particle-os-new cmd/particle_os/main.go

# Verify binary was created
ls -la particle-os-new

# Test new binary
./particle-os-new --version
./particle-os-new --help

# Replace old binary (backup first)
cp particle-os particle-os-old
cp particle-os-new particle-os

# Verify replacement
./particle-os --version

Expected Results

• ✅ Binary compiles without errors
• ✅ New binary shows correct version (0.1.0)
• ✅ Help output shows all available commands
• ✅ Binary size should be similar to original

---

🧪 Step 3: Execute Testing Strategy

3.1 Run Quick Test Suite

# Navigate back to project root
cd /opt/Projects/deb-bootc-image-builder

# Run quick test suite
./scripts/quick-test-suite.sh

Expected Results: All basic functionality tests should pass

3.2 Test Stage Execution (Critical)

# Test apt stage (should work)
./bib/particle-os build --work-dir /tmp/test-apt recipes/minimal-debug.yml --verbose

# Test locale stage (should now work with sudo fixes)
./bib/particle-os build --work-dir /tmp/test-locale recipes/minimal-debug-locale.yml --verbose

# Test complete workflow (should work end-to-end)
./bib/particle-os build --work-dir /tmp/test-complete recipes/simple-cli-bootable.yml --verbose

Expected Results:

• ✅ apt stage completes successfully
• ✅ locale stage completes without permission errors
• ✅ Complete workflow reaches image creation
• ✅ Bootable image is created successfully

3.3 Run Full Test Suite

# Run comprehensive test suite
./scripts/full-test-suite.sh

Expected Results: All tests should pass, indicating the tool is production-ready

---

🚀 Step 4: Validate Production Readiness

4.1 Test All Recipe Types

# Test minimal recipe
./bib/particle-os build --work-dir /tmp/test-minimal recipes/minimal-debug.yml --verbose

# Test locale recipe
./bib/particle-os build --work-dir /tmp/test-locale recipes/minimal-debug-locale.yml --verbose

# Test complete recipe
./bib/particle-os build --work-dir /tmp/test-complete recipes/simple-cli-bootable.yml --verbose

# Test QEMU recipe
./bib/particle-os build --work-dir /tmp/test-qemu recipes/qemu-test.yml --verbose

4.2 Test Image Creation

# Verify images were created
find /tmp/test-* -name "*.img" -o -name "*.qcow2" -o -name "*.vmdk" -o -name "*.vdi"

# Check image properties
ls -lh /tmp/test-*/output/*

# Test image bootability (if QEMU available)
qemu-system-x86_64 -hda /tmp/test-complete/output/simple-cli-bootable.img -m 1024 -nographic

4.3 Test Error Handling

# Test with invalid recipe (should fail gracefully)
./bib/particle-os build --work-dir /tmp/test-error invalid-recipe.yml --verbose

# Test with insufficient disk space (should be prevented)
./bib/particle-os build --work-dir /tmp/test-space recipes/minimal-debug.yml --verbose

---

📊 Step 5: Update Documentation and Status

5.1 Update Project Status

# Update todo file to reflect completion
# Update production readiness percentage
# Mark Phase 4 as complete

5.2 Update User Guides

# Update HOW-TO-USE.md with working examples
# Update HOW-TO-USE-AS-CICD.md with production status
# Update testing strategy with actual results

5.3 Create Production Release Notes

# Document all working features
# List known limitations
# Provide usage examples
# Include troubleshooting guide

---

🎯 Success Criteria

Phase 4 Complete When:

• Binary recompiles successfully with Go 1.21+
• All stage execution tests pass (no permission errors)
• End-to-end workflow completes successfully
• Bootable images are created correctly
• All test suites pass
• Documentation is updated with working examples

Production Ready When:

• All recipe types execute successfully
• All image formats are supported
• Error handling is robust and helpful
• Testing is comprehensive and automated
• Documentation is complete and accurate
• CI/CD integration is validated

🚨 Potential Issues and Solutions

Compilation Issues

# If Go modules are missing
go mod init particle-os
go mod tidy

# If dependencies are missing
go get github.com/sirupsen/logrus
go get github.com/spf13/cobra
go get golang.org/x/sys/unix

Runtime Issues

# If permission errors persist
sudo chown -R $USER:$USER /tmp/particle-os-*

# If disk space issues persist
./scripts/manage-disk-space.sh cleanup
./scripts/manage-disk-space.sh create-work-dir /home/joe/particle-os-builds

Testing Issues

# If tests fail unexpectedly
./scripts/manage-disk-space.sh status
df -h /tmp /home
which parted mkfs.ext4 extlinux qemu-img

📝 Post-Completion Tasks

Immediate (Same Day)

1. Update project status in todo and documentation
2. Test with real-world recipes to validate production readiness
3. Create production release notes documenting capabilities

Short Term (1-2 weeks)

1. Performance testing - measure build times and resource usage
2. Integration testing - validate CI/CD workflows
3. User acceptance testing - test with real use cases

Medium Term (2-4 weeks)

1. Deploy to CI/CD systems for automated testing
2. Create user tutorials and examples
3. Gather feedback and iterate on improvements

---

🎉 Expected Outcome

Once these steps are completed, deb-bootc-image-builder will be:

• ✅ Fully functional - All stages execute successfully
• ✅ Production ready - Reliable and robust operation
• ✅ Well tested - Comprehensive validation completed
• ✅ Well documented - Complete guides and examples
• ✅ CI/CD ready - Automated workflows validated

The tool will have evolved from a working prototype with critical gaps to a production-ready OS image builder that can reliably create bootable images from container recipes.
