• Encryption passphrase required at every boot
• 14+ character minimum with complexity requirements
• No backdoors or recovery without passphrase

✅ Password Complexity (14+ chars, enforced)

• Mandatory: 1 uppercase, 1 lowercase, 1 digit, 1 special character

Check Build Status

When Returning to Work

1. Check if build completed:

   ls -lh output/
   

   Expected output:

   • knel-football-secure-v1.0.0.iso (~1-2GB)
   • knel-football-secure-v1.0.0.iso.sha256
   • knel-football-secure-v1.0.0.iso.md5

2. If build still running, monitor progress:

   # View real-time build log
   tail -f /tmp/knel-iso-build.log
   
   # Check current stage
   tail -50 /tmp/knel-iso-build.log | grep -E "(P: |lb )"
   
   # Check for errors
   grep -i "error\|failed" /tmp/knel-iso-build.log
   

3. If build succeeded, verify output:

   # Check ISO file
   ls -lh output/knel-football-secure-v1.0.0.iso
   
   # Verify checksums
   cd output/
   sha256sum -c knel-football-secure-v1.0.0.iso.sha256
   md5sum -c knel-football-secure-v1.0.0.iso.md5
   
   # Verify file ownership
   stat -c "%U:%G" output/knel-football-secure-v1.0.0.iso
   # Should show: tsys:tsys (your user, not root)

Critical Configuration Notes

• ✅ Use /tmp inside container (NOT mounted volume)
• ✅ --privileged flag (required for mount operations)
• ✅ --user root flag (required by live-build)
• ✅ DO NOT use --linux-packages flag (causes duplicate package names)
• ✅ DO NOT use --memtest flag (missing memtest86+.bin file)
• ✅ DO NOT use --win32-loader true flag (package not available in testing)
• ✅ Pass USER_UID/USER_GID for correct ownership

Issues Encountered and Solutions

Attempt 1: Duplicate Package Names

Error: E: Unable to locate package linux-image-amd64-amd64 Cause: --linux-packages "linux-image-amd64" appended architecture Solution: Removed --linux-packages flag (live-build defaults are correct)

Attempt 2: Permission Denied (tmp/ directory)

Error: rm: cannot remove './cache/...': Permission denied Cause: Previous container created files with restrictive permissions Solution: Build in container's /tmp instead of mounted volume

Attempt 3: Root Privileges

Error: E: Root privileges needed! Cause: Container default user builder (UID 999) Solution: Added --user root flag to docker run

Attempt 4: Mount Permissions

Error: mount: /build/chroot/dev/pts: permission denied Cause: Even root user needs --privileged flag for mount operations Solution: Added --privileged flag to docker run

Attempt 5: Memtest Missing File

Error: cp: cannot stat 'chroot/boot/memtest86+.bin': No such file or directory Cause: --memtest memtest86+ flag installed package but file not created Solution: Removed --memtest memtest86+ flag (ISO works without it)

Attempt 6: Win32-Loader Missing Package

Error: E: Unable to locate package win32-loader Cause: --win32-loader true flag, package not available in Debian Testing Solution: Removed --win32-loader true flag (not needed for modern systems)

Attempt 7 (CURRENT): Minimal Configuration

Status: Running successfully Fixes: Removed all problematic flags, using minimal configuration Result: Build progressing through all stages

2. run.sh - Main entry point with build/test/lint/clean/iso/shell commands
3. AGENTS.md - Docker-only workflow requirements
4. JOURNAL.md - Append-only development journal

Compliance Verification (AGENTS.md)

✅ Docker-Only Workflow

• All operations in Docker container: YES
• Docker volumes used for file I/O: YES
• No directories created in /home: YES
• No host system files modified: YES
• Only final artifacts copied to output/: YES
• File ownership preserved (chown step): YES
• Only docker/git/libvirt on host: YES
• No working directory clutter: YES

Volume Mounting Strategy

/workspace/  # Source (read-only)
/output/      # Final artifacts
/tmp/          # Container build location (not mounted)

If Build Succeeded (Next Steps)

1. Test ISO with libvirt/virsh:

   # Create VM
   virt-install \
     --name knel-football-test \
     --memory 2048 \
     --vcpus 2 \
     --cdrom output/knel-football-secure-v1.0.0.iso \
     --os-variant debian10 \
     --graphics spice
   
   # Test security features:
   # - WiFi/Bluetooth disabled
   # - SSH configuration
   # - Firewall rules
   # - USB automount
   # - QR code import
   

2. Update root run.sh with iso command for future use

3. Document build process in README.md

4. Archive build artifacts in release structure

If Build Failed (Restart)

1. Check error in log:

   tail -100 /tmp/knel-iso-build.log | grep -A 10 "E:"
   

2. Identify stage where it failed (bootstrap/chroot/binary)

3. Use minimal configuration (current working version):

   # See "Build Configuration (Working Version)" section above
   

4. Monitor closely with tail -f /tmp/knel-iso-build.log

Quick Reference Commands

Check Build Status

# Monitor log
tail -f /tmp/knel-iso-build.log

# Check output
ls -lh output/

# Verify ISO (when complete)
ls -lh output/knel-football-secure-v1.0.0.iso
cd output/
sha256sum -c knel-football-secure-v1.0.0.iso.sha256

Restart Build (if needed)

# Kill any existing build containers
docker ps | grep -E "(knel|football)" | awk '{print $1}' | xargs -r docker kill

# Run build command (see "Build Configuration" section)

Clean Build Artifacts

./run.sh clean
# Or manually
rm -rf output/* tmp/* tmp2/*
