As a user of embedded Node.js - I need the ability to package JavaScript into the binary and feed it to Node.js without writing it to disk.

My current flow is to literally embed the JavaScript in the binary, then on start, write the JavaScript code to `/tmp/{random}` and point Node.js to execute the code at that destination.

A virtualized filesystem also allows for a safer "plugin" story for Node.js - where JavaScript plugins can be prevented from accessing the real filesystem.
