# ProxMenux - NFS Host Manager for Proxmox Host
# ==========================================================
# Author : MacRimi
# Copyright : (c) 2024 MacRimi
# License : GPL-3.0
# https://github.com/MacRimi/ProxMenux/blob/main/LICENSE
# Version : 1.0
# ==========================================================
# Description:
# Mounts an external NFS export on the Proxmox host.
# User picks one or both methods:
# 1. As Proxmox storage (pvesm add nfs) → /mnt/pve/<id>
# 2. As host fstab mount → user-chosen path
#
# Method 2 is for users who want the host to mount the share
# for LXC bind-mounts WITHOUT exposing it as a Proxmox storage
# in the Datacenter UI. The mount path is opened up so
# unprivileged LXCs can read/write through a bind-mount —
# all permission tweaks happen on the host side, NEVER inside
# the container.
#
# Features:
# - Auto-discover NFS servers on the local subnet (nmap).
# - Reachability validation chain (ping + nc + showmount).
# - Content-type checklist (import/backup/iso/vztmpl/images/
# rootdir/snippets).
# - View, remove and connectivity-test for existing storages.
