# Template for enhancing VM YAML files - use as reference

# This script shows the pattern for enhancing VM YAML files
# Apply these changes to each VM file:

# 1. Add packages after lsb-release:
#        - chrony
#        - unattended-upgrades
#        - apt-listchanges

# 2. Add NTP configuration after package_upgrade:
#      # Time synchronization (NTP)
#      ntp:
#        enabled: true
#        ntp_client: chrony
#        servers:
#          - 0.pool.ntp.org
#          - 1.pool.ntp.org
#          - 2.pool.ntp.org
#          - 3.pool.ntp.org

# 3. Update package verification:
#    for pkg in qemu-guest-agent curl wget net-tools chrony unattended-upgrades; do

# 4. Add security configuration before final_message:
#        # Configure automatic security updates
#        # Configure NTP (Chrony)
#        # SSH hardening

# 5. Add write_files section before final_message:
#      write_files:
#        - path: /etc/apt/apt.conf.d/20auto-upgrades
#          content: |
#            APT::Periodic::Update-Package-Lists "1";
#            APT::Periodic::Download-Upgradeable-Packages "1";
#            APT::Periodic::AutocleanInterval "7";
#            APT::Periodic::Unattended-Upgrade "1";
#          permissions: '0644'
#          owner: root:root

# 6. Enhance final_message with comprehensive status
