I'm interested- this sounds cool.. (I've used Cinelerra a bit for a
project I did last year)

I also got a PXE boot environment, that either boots to a "which version
of 8.04 do you want to install" or full on LTSP environment..

Not quite what you are after, but the PXE bit is there and working.

So I did some digging around for the rest, and found this..


You have effectively got an image sorted - so judging by the guide
linked above you may be able to put you image in place of the ones as
listed (Clonezilla/Ubuntu live CD)

I am gonna give this a whirl myself in the next few days (maybe not with
the Cinelerra, I don't know enough on setting up clients for rendering,
nor have anything TO render - but at least the "live boot" CD) - I'll
report on my milage.
