# ProxMenu - A menu-driven script for Proxmox VE management
# ==========================================================
# Author : MacRimi
# Copyright : (c) 2024 MacRimi
# License : MIT (https://raw.githubusercontent.com/MacRimi/ProxMenux/main/LICENSE)
# Version : 1.0
# Last Updated: 28/01/2025
# ==========================================================
# Description:
# This script allows users to assign physical disks to existing
# Proxmox containers (CTs) through an interactive menu.
# - Detects the system disk and excludes it from selection.
# - Lists all available CTs for the user to choose from.
# - Identifies and displays unassigned physical disks.
# - Allows the user to select multiple disks and attach them to a CT.
# - Configures the selected disks for the CT and verifies the assignment.
# ==========================================================
