Linux Server Virtual File System Internals with FUSE

In episode 98 of Linux Server Admin with Fexingo, Lucas and Luna dive into the world of FUSE — Filesystem in Userspace. They explain how FUSE lets you build custom file systems without kernel modules, walk through a real example of mounting an S3 bucket as a local directory using s3fs-fuse, discuss performance trade-offs (context-switch overhead vs. development speed), and share practical tips for when FUSE makes sense (and when it doesn't). Perfect for sysadmins who've wondered how tools like rclone, sshfs, or EncFS work under the hood or who need to extend a server's storage without patching the kernel. Includes a light-touch listener-support moment.
