NodeOS provides a powerful kernel image that bundles NodeJS with the Linux
kernel. nos-init can be used to bundle up a NodeJS module into an initramfs
that can be used along side the NodeOS kernel.
Run nos-init in the directory containing the package.json, or provide the path
to said directory on the commandline. nos-init will produce on stdout the
compressed cpio file; use your shell to redirect it to a file.
nos-init walks the indicated directory, including all the files and
subdirectories, and additionally produces the file /sbin/init. This is set to
run the script pointed to by 'main' in the package.json file, or failing that,
server.js or index.js.
