An OS with a file system entirely in RAM?

Question

Operating Systems

I just wonder if it's possible to somehow organize this, I personally recently learned about the ram disk, or rather that they are actually easy to use with the right software, and I decided to immediately install the virtual machine on the ram disk, the result was pretty good
But all- However, in a virtual machine, you can’t use the resources of the computer to the fullest .. but I would like to use at least some toys and software) .. With my 8 gigs it’s almost unreal, but it’s still interesting about the implementation
... did, only without a virtual machine?
