- Dependency analysis via readelf -d
- Recursive transitive dependency resolution
- Library copying with path preservation
- Binary search in standard Linux paths

- Dependency Analysis: Parse
readelf -doutput to find shared library dependencies - Recursive Resolution: Trace full dependency tree including transitive dependencies
- Library Copying: Copy binaries with all required libraries to a target directory
- Path Search: Find binaries and libraries in standard Linux paths

"usr/lib", // dest lib path
&["usr/libexec/sudo"], // extra search paths
&["systemd"], // private lib dirs (use &[] for musl/OpenRC)
)?;
// Find a binary in standard paths
if let Some(path) = find_binary(source_root, "bash") {
println!("Found bash at: {}", path.display());

}ldd executes the binary to resolve dependencies, which fails for cross-compiled binaries and can be a security risk. readelf -d parses the ELF headers directly without execution.
