Summary

Fully Compliant ✅

• Filesystem structure (100%)
• Configuration layout (100%)
• Data layout (100%)
• Log and runtime directories (100%)
• Core component installation (100%)

Additional Components Installed

Beyond the architecture spec, the installer also includes:

1. File Sharing Services

   • NFS Server (for NFS shares)
   • Samba (for SMB/CIFS shares)

2. Antivirus Service

   • ClamAV (for Share Shield functionality)

3. Additional Configuration Directories

   • /etc/calypso/nfs/ - NFS configuration
   • /etc/calypso/samba/ - Samba configuration
   • /etc/calypso/clamav/ - ClamAV configuration

These additions are necessary for the full functionality of the Calypso appliance as implemented.
