Live ISO over http

[lawnmover]

Whats the layout of the liveCD? Kernel and intrd for sure. But what with the rest. Or did you pack the whole fs into the initrd?
I have a pxe configuration for the net isntaller. I had to load the squashfs file that holds the actuall filesystem over http using the kernel command line linus fetch=http://www.your.domain/path/to/squash.fs.
