🌙 LunaFS

LunaFS is a lightweight experimental filesystem written in C with a FUSE-based Linux driver and support for both disk image files and physical block devices.

Important

LunaFS is experimental. Do not use on drives or partitions containing important data.

✨ Features

• Custom filesystem layout (superblock, inodes, data blocks).
• Works with both image files (lunafs.img) and physical drives (/dev/sdX).
• Includes:
  • lunafs_fuse → FUSE driver to mount LunaFS in userspace.
• Mounts like a normal filesystem → browsable in Dolphin, Nautilus, etc.
• Optional -o allow_other support for sharing mounts across users.
