Creating a custom Live build of Ubuntu with work in RAM

You need to create a custom Ubuntu Live image (or compatible system) that loads entirely into RAM at startup, without using a USB flash drive or disk after booting.

Main requirements:

1. Base system:
   Ubuntu (version to be discussed) or another compatible system supporting Live-mode.
2. Full RAM loading:
   The Live system must boot with the parameters toram, nopersistence, noeject so that all files and processes operate exclusively in RAM.
   🔸 IMPORTANT:
   The system should not work with a persistent filesystem. No changes or installed programs are saved after reboot.
   This is not a persistent live USB, but a one-time RAM session that is completely cleared after shutdown.
3. Support for MacBook with T2 chip:
   • Kernel with T2 patches (can be taken from the T2-Ubuntu project on GitHub)
   • Required .deb packages with kernel drivers and modules for T2
   • Keyboard, touchpad, and internet (Wi-Fi/Bluetooth) must definitely work.
4. 
   
5. Pre-installed packages:
   • Several necessary programs
   • Drivers for BCM WiFi/Bluetooth
