I think you might be confusing the concept of network booting with the 
concept of a networked file system.  The fact that a given machine can 
use a network card to download a boot image is one thing, and the fact 
that an operating system can share data over a network via a 
POSIX-compatible mechanism is entirely another.

Hypothetically yes - as i mentioned in my previous email, in theory 
there's nothing stopping you from integrating Gluster (and the necessary 
support tools / libraries) into your boot image.
