I am curently developing a file system for my OS (D.eSystem) with the version 6.1.0.5. The file system is now not working,but it is in development, you can find D.eSystem 6.1.0.5 here: https://github.com/D-electronics-scratch/all_D.eSystem_versions/releases/tag/v.6.1.0.5
Very cool. It’s hard to get into file system development because it’s a very small audience that’s willing to test, and it takes years to build trust. Administrators prefer boring and rock solid stability which is not typically conducive to innovation in this area.
