Unconventional Linux Filesystems: OverlayFS, IncFS, ZoneFS, LTFS, and StegFS

The article surveys several unconventional Linux filesystems—OverlayFS for layered read‑only overlays, IncFS enabling incremental app loading, ZoneFS exposing zoned block device zones, LTFS bringing true file‑system semantics to magnetic tape, and StegFS hiding data steganographically—highlighting their unique designs and use cases.

Read-only Compressed File Systems: CramFS, SquashFS, CromFS, and EROFS Comparison

Read‑only compressed file systems such as CramFS, SquashFS, CromFS, and the newer EROFS provide space‑saving, non‑writable storage for embedded devices, with CramFS limited by small file and filesystem sizes, SquashFS offering large limits and flexible chunking, CromFS focusing on maximal compression, and EROFS improving performance and memory usage through fixed‑output LZ4 compression and in‑place decompression.
