[split] Possible To Load Snakeoil OS in RAM

[agent_kith]

Please excuse for a layman question...... does PxE booting also can boot without a boot disc?  So the whole OS is already in the RAM?

Yes. That's the idea, one less SSD running on the machine means less load on the PSU. And faster since everything is running in RAM.

You can look at this article for a general idea, and look up the Internet for more resources on how to do this.
