FUSE-T
FUSE-T is a kext-less implementation of FUSE for macOS that uses NFS v4 local server instead of a kernel extension. The main motivation for this project is to replace macfuse (https://osxfuse.github.io/) that implements its own kext to make fuse work. With each version of macOS it's getting harder and harder to load kernel extensions. Apple strongly discourages it and, for this reason, software di

ZFS is a hybrid filesystem and volume manager system that is quite popular recently but has some important and unexpected probl ems. It has many good features, which are probably why it is used: snapshots (with send/receive suppport), checksumming, RAID of some kind (with scrubbing support), deduplication, compression, and encryption.

What is a bind mount?
A bind mount is an alternate view of a directory tree. Classically, mounting creates a view of a storage device as a directory tree. A bind mount instead takes an existing directory tree and replicates it under a different point. The directories and files in the bind mount are the same as the original. Any modification on one side is immediately reflected on the other side, since the two views sho

TFS was created out of the need for a modern file system for Redox OS, as a replacement for ZFS, which proved to be slow to implement because of its monolithic design.
