Subject: [PATCH 2/4] Fix hard-coded paths and add comprehensive build-iso.sh
 script

- Remove all hard-coded paths (/home/ubuntu/SecureOS, /mnt/projects)
- Use PROJECT_DIR dynamically in all build scripts
- Add comprehensive build-iso.sh at root with v5.0.0 integration
- Update .gitignore for build-output directory
- Improve error handling and path flexibility

 ## Troubleshooting Build Issues
 
 ### Error: "Not enough disk space"
-- Free up at least 10GB
-- Build uses `/tmp/secureos-build` (needs 5-8GB temp space)
+**Solution:**
+- Free up at least 15GB (20GB recommended)
+- Build uses `/tmp/secureos-build` (needs 8-12GB temp space)
+- Check with: `df -h /tmp`
 
 ### Error: "Permission denied"
-- Must run with `sudo`
-- Check file permissions
+**Solution:**
+- Must run with `sudo` or as root
+- Check file permissions with: `ls -la build-iso.sh`
+- Make executable: `chmod +x build-iso.sh`
 
 ### Error: "Failed to download packages"
-- Check internet connection
+**Solution:**
+- Check internet connection: `ping archive.ubuntu.com`
 - Try different mirror in sources.list
+- Update package lists: `sudo apt-get update`
 - Retry the build
 
+### Error: "This script must be run as root"
+**Solution:**
+- Run with sudo: `sudo ./build-iso.sh`
+- Or switch to root: `sudo su -` then run the script
+
 ### Build Hangs or Freezes
-- Check system resources (RAM, CPU)
+**Solution:**
+- Check system resources: `htop` or `free -h`
 - Kill and restart: `sudo killall debootstrap`
 - Clear temp: `sudo rm -rf /tmp/secureos-build`
+- Check logs: `tail -f build.log`
 
 ### Error: "Invalid GPG signature"
+**Solution:**
 - Update GPG keys:
   ```bash
   sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys [KEY_ID]
   ```
 
+### Error: "grub-mkrescue: command not found"
+**Solution:**
+- Install GRUB tools:
+  ```bash
+  sudo apt-get install grub-pc-bin grub-efi-amd64-bin
+  ```
+
+### Error: "mksquashfs: command not found"
+**Solution:**
+- Install squashfs-tools:
+  ```bash
+  sudo apt-get install squashfs-tools
+  ```
+
+### Python Dependencies Missing (v5.0.0 features)
+**Solution:**
+- Install Python packages:
+  ```bash
+  sudo apt-get install python3-pip python3-dev
+  sudo pip3 install numpy scikit-learn cryptography pynacl
+  ```
+
+### Build fails during chroot
+**Solution:**
+- Check if filesystems are mounted: `mount | grep secureos-build`
+- Unmount manually:
+  ```bash
+  sudo umount /tmp/secureos-build/chroot/{dev/pts,sys,proc,run,dev}
+  ```
+- Clean and retry
+
+## Dependency Management
+
+### Required Build Dependencies
+
+The build scripts automatically check and install required dependencies. These include:
+
+- **debootstrap**: Bootstrap base system
+- **squashfs-tools**: Create compressed filesystem
+- **xorriso**: Create ISO images
+- **isolinux**: Boot loader for ISO
+- **syslinux-efi**: EFI boot support

+If you prefer to install dependencies manually before building:
+
+```bash
+sudo apt-get update
+sudo apt-get install -y \
+    debootstrap \
+    squashfs-tools \
+    xorriso \
+    isolinux \
+    syslinux-efi \
+    grub-pc-bin \
+    grub-efi-amd64-bin \
+    mtools \
+    dosfstools \
+    git \
+    python3 \
+    python3-pip

+```bash
+sudo pip3 install numpy scikit-learn cryptography pynacl
+```
+
 ## Build Cleanup
 
 After successful build:
 ```bash
-# Temporary build files are auto-cleaned
+# Temporary build files are auto-cleaned by the script
 # But you can manually clean with:
 sudo rm -rf /tmp/secureos-build
+
+# Clean all build artifacts:

+## Build Verification
+
+After building, verify the ISO integrity:
+
+### Automated Verification (Recommended)
+
+Run the verification script to perform comprehensive checks:
+```bash
+./verify-iso.sh
+```
+
+This script checks:
+- ISO file existence and size
+- SHA256 and MD5 checksums
+- ISO format and bootability
+- Essential ISO contents (kernel, initrd, filesystem)
+- Build log for errors
+
+### Manual Verification
+
+Check the SHA256 checksum manually:
+```bash
+cd iso-build
+sha256sum -c SecureOS-1.0.0-amd64.iso.sha256
+```
+
+Expected output:
+```
+SecureOS-1.0.0-amd64.iso: OK
+```

 ## Next Steps After Building
 
-1. **Verify the ISO**:
+1. **Verify the ISO** (see Build Verification section above)
+
+2. **Test in VM** before deploying to production:

+
+**Usage:**
+```bash
+sudo ./build-iso.sh
+```
+
+### 2. Standard Build Scripts
+
+**Location:** `scripts/` directory
+
+#### `scripts/build_iso.sh`
+- Standard build with all security features
+- Fixed all hard-coded paths
+- Uses dynamic `${PROJECT_DIR}` variable
+- Enhanced error handling
+
+#### `scripts/build_iso_fast.sh`
+- Fast build with minimal packages for testing
+- Fixed all hard-coded paths
+- Reduced build time (15-30 minutes)
+
+#### `scripts/build_iso_local.sh`
+- Build using local package mirror
+- For airgapped or offline builds
+
+#### `scripts/build_iso_with_local_mirror.sh`
+- Custom mirror configuration
+- Enterprise deployment support
+
+### 3. ISO Verification Script (`verify-iso.sh`)
+
+**Purpose:** Automated ISO integrity and completeness verification
+
+**Checks Performed:**
+- ✅ ISO file existence and size validation
+- ✅ SHA256 and MD5 checksum verification
+- ✅ ISO format validation (ISO 9660)
+- ✅ Essential components presence:
+  - Kernel (vmlinuz)
+  - Initial RAM disk (initrd)
+  - Root filesystem (squashfs)
+  - Bootloader (GRUB)
+- ✅ Build log analysis for errors
+- ✅ Colored output with pass/fail/warning indicators
+
+**Usage:**
+```bash
+./verify-iso.sh
+```
+
+### 4. Build System Test Suite (`test-build-system.sh`)
+
+**Purpose:** Validate build system setup without requiring root
+
+**Test Categories:**
+- Build script files existence and permissions
+- Bash syntax validation
+- Hard-coded path detection
+- Documentation completeness
+- CI/CD configuration
+- v5.0.0 security features presence
+- Configuration files
+- Build script features (dynamic paths, dependencies, error handling)
+
+**Usage:**
+```bash
+./test-build-system.sh
+```
+
+### 5. Enhanced Documentation
+
+#### `BUILD.md` Updates
+- ✅ Added v5.0.0 security features section
+- ✅ Enhanced system requirements (15GB disk, multi-core CPU)
+- ✅ Multiple build script options documented
+- ✅ Comprehensive dependency management section
+- ✅ Expanded troubleshooting guide (10+ common issues)
+- ✅ Build verification instructions
+- ✅ Python dependencies for v5.0.0 features
+- ✅ Manual dependency installation guide
+- ✅ Build cleanup procedures
+
+#### `scripts/README.md`
+- Already comprehensive, covers all utility scripts
+- Documents build scripts, maintenance tools, testing
+
+### 6. CI/CD Integration
+
+**GitHub Actions Workflow:** `.github/workflows/build-iso.yml`
+
+**Enhancements:**
+- ✅ Updated to use new `build-iso.sh`
+- ✅ Added automated ISO verification step
+- ✅ Enhanced release notes with v5.0.0 features
+- ✅ Maximized build space for larger ISO
+- ✅ Artifact upload with proper compression
+- ✅ Automated release creation on tags
+
+**Workflow Features:**
+- Runs on: `ubuntu-24.04`
+- Triggers: Push to master/main, tags, manual dispatch
+- Maximized build space (removes unnecessary components)
+- Automated dependency installation
+- ISO verification after build
+- Checksum generation
+- 30-day artifact retention
+- Automated GitHub releases
+
+### 7. Configuration Updates
+
+#### `.gitignore`
+Added build artifact directories:
+- `iso-build/` - ISO output directory
+- `build-output/` - Package build directory
+- `build.log` - Build log file
+
+#### `build.sh` (Root)
+- Fixed hard-coded `/mnt/projects` path
+- Now uses `${PROJECT_DIR}/build-output`
+
+## Path Management
+
+### Problem Solved
+All hard-coded paths (`/home/ubuntu/SecureOS`, `/mnt/projects`) have been removed.
+
+### Solution Implemented
+All scripts now use dynamic path detection:
+```bash
+PROJECT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
+ISO_OUTPUT_DIR="${PROJECT_DIR}/iso-build"
+```
+
+### Verification
+```bash
+# No hard-coded paths should be found:
+grep -r "/home/ubuntu\|/mnt/projects" build.sh build-iso.sh scripts/build_iso*.sh
+```
+
+## Dependency Management
+
+### Automatic Dependency Checking
+The main `build-iso.sh` script includes comprehensive dependency checking:
+
+**Required Tools:**
+- debootstrap - Bootstrap base system
+- squashfs-tools - Create compressed filesystem
+- xorriso - Create ISO images
+- isolinux - Boot loader
+- syslinux-efi - EFI boot support
+- grub-pc-bin - GRUB for BIOS
+- grub-efi-amd64-bin - GRUB for UEFI
+- mtools - DOS filesystem tools
+- dosfstools - FAT filesystem tools
+- git - Version control
+
+**Python Dependencies:**
+- python3 - Core Python runtime
+- python3-pip - Package installer
+- python3-dev - Development headers
+- numpy - Numerical computing
+- scikit-learn - Machine learning
+- cryptography - Cryptographic operations
+- pynacl - Networking and cryptography
+
+### Installation
+Dependencies are automatically installed when missing. Manual installation:
+```bash
+sudo apt-get update
+sudo apt-get install -y debootstrap squashfs-tools xorriso \
+    isolinux syslinux-efi grub-pc-bin grub-efi-amd64-bin \
+    mtools dosfstools git python3 python3-pip python3-dev
