Re: Booting Live-ISO over PXE+HTTP using Grub loopback

Hi and thanks for the input.
Indeed I have made some progress.

This is the best solution, so let's try this path.
1. First the simpler case if you don't mind:
menuentry "Ubuntu-amd64-desktop-13.04.iso" {
  set root="http,192.168.2.100"
  set isofile="ubuntu-13.04d-amd64.iso"
  loopback loop0 ($root)$isofile
  linux (loop0)/casper/vmlinuz.efi boot=casper fromiso=$isofile httpfs=($root)$isofile
  initrd (loop0)/casper/initrd.lz  }

This did not work. Grub will fetch the initrd file normally, so it must be my syntax.
* Should "fromiso=" be full path "($root)$isofile"?
* How is the param "live-media-path=" used? Would this work?
  linux (loop0)/vmlinuz.efi boot=casper live-media-path=casper
* Any other suggestions in above syntax appreciated.

2. Now the slightly tougher case: I need to better understand the media I had previously downloaded so that I can accurately debug why Debian-Jessie fails to mount.
I have the i386-lxde-CD-1.iso from 07-2014. Am I to understand that:
/install.386 => live installer
/install.386/gtk => live desktop system

* Can I run the installer AND a live-system from this iso, or just the installer?
* This fails, so I must again be missing some syntax:
  set root="http,192.168.2.100"
  set isofile="debian-testing-i386-lxde-CD-1.iso"
  loopback loop0 ($root)$isofile
  linux (loop0)/install.386/vmlinuz boot=live fromiso=$isofile httpfs=($root)$isofile
  initrd (loop0)/install.386/initrd.gz  }

Thanks and regards.
