No, that's not how union filesystems work. There is no "flush"
operation; the "lower" filesystem is never changed, all changes are
written to the "upper" filesystem (which in your scenario would be a
ramfs). In your scenario, all changes will be lost on reboot.

What you describe is basically a cache, which all modern OSes have,
with automatic "flush" :)
