🚀 Nofus - The NFS Mount Guardian

Nofus is a blazingly fast and memory-safe Rust-powered daemon that vigilantly monitors your NFS mounts and triggers custom actions based on their availability. Never get caught with stale mounts again! 🛡️

✨ Features

• 🕵️ Real-time NFS Mount Monitoring using Linux inotify
• ⚡ Configurable System Commands for mount/unmount events
• 🧪 Dry-Run Mode for safe testing
• 📊 Verbose Logging for deep insights
• 🔄 Periodic Health Checks (configurable interval)
• 📁 YAML Configuration for easy setup

📦 Installation

1. Prerequisites: Ensure you have Rust installed (1.60+)

   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
   

2. Install Nofus:

   cargo install nofus
   

⚙️ Configuration

Create config.yml in your $HOME/.config/nofus directory:

# Sample Configuration
mount_points:
  - "/mnt/nfs/share1"
  - "/media/cloud_storage"

delay_seconds: 5  # Check interval

# Commands to execute (supports full shell syntax)
all_mounted_cmd: "systemctl start my-app.service"
any_unmounted_cmd: "systemctl stop my-app.service && wall 'NFS Crisis!'"

Note: If you start nofus without creating a configuration file first, one will be created from a template and nofus will exit.

🚦 Usage

nofus [OPTIONS]

Options:

• --dry-run: Simulate without executing commands
• --verbose: Show debug-level logging

Example:

nofus --verbose --dry-run
