Re: [ros-dev] A reimplementation of reactos' cache manager supporting alternate filesystems better (including ext2)

[James Walmsley]

Hi,

The other day I had an idea. Because Linux has already many
file-systems, would it not be possible to simply make a generic FS
driver, that simply wraps around the Linux fs model?

I'm sure the linux and windows models are quite different when it
comes to their overall architecture.

The advantage of doing this would be that we'd have instant access to
well tested and maintained code.

This is essentially what Aleksey is doing with my FullFAT library,
albeit with a few small modifications.

Kind Regards

James
