Indeed, I'm looking into gPXE to boot from an http-served iso. Hopefully that will scale better...
I don't know what you intend to achieve but you cannot do random seeks over http, so it will still download the entire iso file. Have a good look at archiso, maybe it has some optimizations for pxe.
Indeed, but tftp has limitations that http does not, and is (from what I've read) generally faster than tftp - so even though it downloads the entire file, it should be faster.
well, apparently you can: https://en.wikipedia.org/wiki/Byte_serving still, i wonder how you would actually go about it in practice. and what kind of latencies to expect.
Oh, that's interesting. Not what I was trying to achieve, but I might have a play once I've got something basic working. I'll definitely take a closer look at archiso once I've understood the basics. If a simple tftp- or http-served iso, plus aif script, works then I'll have a baseline to compare with.
