Show HN 介绍了一个非官方的 FUSE 虚拟文件系统，可将 Proton Drive 挂载为 Linux 本地文件夹，支持按需下载、事件同步和延迟写入上传。项目仍处早期阶段，尚未获得 Proton 官方支持。
Vercel's Sandbox now supports running Docker and FUSE filesystems without constraints, enabling developers to mount S3 buckets and network filesystems, and share state across sandboxes. This update is built on MicroVMs for instant boot and unconstrained runtimes.
A vulnerability in the Linux kernel's FUSE readdir cache (CVE-2026-31694) allows unprivileged local users to escalate to root via an out-of-bounds write. The bug affects many desktop distributions and can be exploited by mounting a FUSE filesystem.
This article walks through building a minimal FUSE filesystem in Rust called magicfs, which uses a metadata.json and blob files as a backing store, demonstrating core filesystem concepts like name lookup, inode stability, and kernel caching.
microsandbox replaced its slow user-space FUSE filesystem with a kernel-mounted EROFS disk image, achieving a 47× geometric mean speedup across filesystem operations and eliminating the VM/host round-trip bottleneck.
Julia Evans created a tool called git-commit-folders that mounts git commits as folders using NFS (and FUSE), allowing users to explore old commits like directories.
