[split] Possible To Load Snakeoil OS in RAM

[wxrbbs]

Suggestion: Is it possible to run programs in memory, or even run the system in memory (such as ramroot)? Currently, after implementing memory-resident operation for mpd, upmpdcli, and diretta, the sound quality has improved significantly. Therefore, have you considered developing in this direction?

As in load the OS in memory? Technically it can be done just that it requires some advanced networking configuration (e.g. setting up a TFTP server, and configure your computer to boot from network). Doing so it means you can boot your machine without any HDD/SSD.

I have a blog talking about it here: PxE booting.

Video of diskless setup.

Yes, interesting. AudioLinux offers this option:

7) With ramroot option you can load the entire system to RAM for a record reactivity and general performance. This way you can run a system without drives

Ramroot is slightly different from PxE booting though. With PxE booting you can do so with any Linux operating systems. Ramroot is designed for Arch Linux but may work with other Linux distros....

Guess I can investigate how Arch Linux works with Snakeoil, and if it's good, maybe migrate over? Something in the medium to long term I guess.

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.
