Module overlay 

Inspect FUSE overlay files and identify modified blocks.

This command analyzes overlay files created by the FUSE mount (in read-write mode) to display which blocks have been modified. The overlay tracks writes at 4 KiB granularity via a separate .meta sidecar file, allowing fast inspection without scanning the (potentially large) overlay data file.

Common Usage

hexz overlay vm-state.overlay             # summary
hexz overlay vm-state.overlay --blocks    # block count + size
hexz overlay vm-state.overlay --files     # list individual block indices

Functions

run

Show statistics or block indices for a FUSE overlay file.
