I don't understand why you call this on demand, but then use a source
client to stream it, that's not really on-demand, that's still
considered streaming.

On demand is usually considered something where the content is always
started from the beginning (unless client and server explicitly
implement resume).

What is a "linked file"? What does this mean?

Given that the file names here match the file names in 3) (except the
m3u/cfg file extension), I'm going to guess that those are play lists
that then are being streamed.

This is most certainly NOT necessary. What would make you think that you
need to do this?
Also why are you not using an init script?

I'm not familiar with Icegenerator.
Have you tried reading its documentation?
http://www.becrux.com/index.php?page=projects&name=icegenerator

If that doesn't fit your bill you could switch to a different source
client that's capable to reload its play list dynamically. That might be
e.g. ez-stream, but there are many.


Cheers
