Ubuntu zRAM Setup

This script automates the removal of the slower virtual memory swapfile and installs/configures zRAM as swap, which provides faster and more modern memory swapping for Linux and Ubuntu-based systems.

🚀 Features

• Removes the old and slow swapfile
• Enables ZRAM as swap using zram-config
• Installs and activates EarlyOOM (a mechanism that prevents system freezes due to low memory)

🛠️ Requirements

• Ubuntu 24.04 and later or derivatives (Kubuntu, Linux Mint, Zorin OS...)
