Overview

The CPIO loader provides read-only access to CPIO archives used as initial ramdisks (initrds). The loader extracts files from the CPIO archive passed by the Limine bootloader as a module.

VFS Integration

The CPIO loader integrates with the VFS layer to present archive contents as a filesystem.
