# ProxMenux - Complete Post-Installation Script with Registration
# ==========================================================
# Author : MacRimi
# Copyright : (c) 2024 MacRimi
# License : MIT (https://raw.githubusercontent.com/MacRimi/ProxMenux/main/LICENSE)
# Version : 1.0
# Last Updated: 06/07/2025
# ==========================================================
# Description:
#
# The script performs system optimizations including:
# - Repository configuration and system upgrades
# - Subscription banner removal and UI enhancements
# - Advanced memory management and kernel optimizations
# - Network stack tuning and security hardening
# - Storage optimizations including log2ram for SSD protection
# - System limits increases and entropy generation improvements
# - Journald and logrotate optimizations for better log management
# - Security enhancements including RPC disabling and time synchronization
# - Bash environment customization and system monitoring setup
#
# Key Features:
# - Zero-interaction automation: Runs completely unattended
# - Intelligent hardware detection: Automatically detects SSD/NVMe for log2ram
# - RAM-aware configurations: Adjusts settings based on available system memory
# - Comprehensive error handling: Robust installation with fallback mechanisms
# - Registration system: Tracks installed optimizations for easy management
# - Reboot management: Intelligently handles reboot requirements
# - Translation support: Multi-language compatible through ProxMenux framework
# - Rollback compatibility: All optimizations can be reversed using the uninstall script
#
# This script is based on the post-install script cutotomizable
# ==========================================================
