-# WALLARM NODE DEPLOYMENT SCRIPT - V1.7 (LXC KERNEL & SOCKET FIX)
+# WALLARM BULLETPROOF STEALTH DEPLOYER - V1.8 (LXC & CENTOS OPTIMIZED)
 # ==============================================================================
 # Features:
-# - Added: Storage driver fallback (vfs) for LXC environments
+# - OS-agnostic binary deployment (CentOS, RHEL, Ubuntu, Debian, Alpine)
-# - Added: Cgroup/Systemd bypass for nested container execution
+# - LXC Hardening: cgroupfs driver + VFS storage for nested container support
-# - Added: socket readiness loop to prevent 'Cannot connect to daemon' errors
+# - Stealth Proxy support (ct.sechpoint.app & hub.ct.sechpoint.app)
-# - Stealth Binary Pull via ct.sechpoint.app (Proxy to download.docker.com)
+# - Comprehensive Pre-flight: EU/US cloud connectivity, CPU/RAM, Architecture
-# - Stealth Image Pull via hub.ct.sechpoint.app (Proxy to registry-1.docker.io)
+# - Reliability: Socket readiness loops, ExecStartPre cleanup, and libseccomp
+# - Verification: Handshake testing, Cloud sync checks, and Attack simulation
+# - Persistence: Systemd service management and log rotation
 # ==============================================================================
