# 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**
```bash
# 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**
```bash
# 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**
```bash
# 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**
```bash
# 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)**
```bash
# 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**
```bash
# 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**
```bash
# 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**
```bash
# 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**
```bash
# 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**
```bash
# Update todo file to reflect completion
# Update production readiness percentage
# Mark Phase 4 as complete
```

### **5.2 Update User Guides**
```bash
# 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**
```bash
# Document all working features
# List known limitations
# Provide usage examples
# Include troubleshooting guide
```

## 🚨 **Potential Issues and Solutions**

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