Copy OS to tmpfs from initramfs
I am putting together a new server with 64GB of RAM and I would like to copy the whole Linux OS into RAM from the disk and run the operating system solely from RAM.
How can I do this?
This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
Most Live CDs have an option to 'Run from RAM'.
