[GTALUG] Recommendations for a root filesystem

There is md-cache or you could try bcachefs.

I have used md-cache caching to SSD and it looks to make a really 
significant speed improvment.

I tried bcache a few years ago but it was a pain since it was not yet 
integrated into the Fedora code base and although bcachefs looks 
interesting I believe its still a case of build your own kernel to run it.
