What does FSFS stand for as related to subversion?

Question

I have scoured the internet looking for a clear answer and cannot find one. What does it stand for? I am currently trying to set up a new repo for our development team and I would like to know what this term means.

Answer 1

FSFS stands for a "filesystem atop of the filesystem" or in the original Subversion 1.1. release notes when FSFS was released, "...a Filesystem implementation that uses the OS filesystem to store data".

Answer 2

I think it's File system file system - which seems silly. the red book don't actually define it
