What does HackerNews think of libfuse?
The reference implementation of the Linux FUSE (Filesystem in Userspace) interface
Language:
C
It seems to me that an alternative could be to simply pair FUSE with any standard file explorer.
The situation is much worse than I had imagined; the parent project, libfuse, is also in need of a maintainer.
FUSE (Filesystem in Userspace) is an interface for userspace programs to export a filesystem to the Linux kernel. The FUSE project consists of two components: the fuse kernel module (maintained in the regular kernel repositories) and the libfuse userspace library (maintained in this repository). libfuse provides the reference implementation for communicating with the FUSE kernel module.
Misleading headline: only FUSE for MacOS became closed source. Linux and Windows FUSE are still open source:
I'd recommend using FUSE for experimentation. You won't have to like hack on the kernel and rebuild it all the time and stuff.
