Module initramfs 

Real initramfs builder producing valid cpio archives (newc format).

The cpio “newc” (SVR4 with no CRC) format is what the Linux kernel expects for initramfs archives. Each entry consists of a 110-byte ASCII header followed by the filename (NUL-terminated, padded to 4-byte boundary), followed by the file data (padded to 4-byte boundary).

The archive is terminated by a trailer entry with the name “TRAILER!!!”.
