The Best fsprotect Alternatives for Robust Filesystem Protection
fsprotect is a powerful set of scripts designed for Debian systems to secure existing filesystems. Leveraging AUFS and initramfs magic, it offers read-only protection for your root filesystem and other partitions, making it an excellent choice for public computers in libraries, labs, and similar environments. While fsprotect excels at preventing accidental damage, simplifying administration, and even speeding up filesystem access, it does come with limitations like predefined change limits and a heavy reliance on swap space due to its use of tmpfs. If these drawbacks are a concern, or you're simply looking for a different approach to filesystem protection, exploring a reliable fsprotect alternative is essential.
