[syslinux] booting clonezilla *.iso via PXE fails

My PXE server: updated to syslinux 4.01-pre1 - no other behaviour.

The clonezilla isos: "wrapped" from Ubuntu into *.iso

The "karmic" clonezilla version has the syslinux-3.84 packet (and uses  
"union=aufs"), the "lucid" clonezilla version has the syslinux-3.86  
packet.

The "isolinux.cfg" ("karmic" version) on the iso has the block

# Since no network setting in the squashfs image, therefore if
# ip=frommedia, the network is disabled. That's what we want.

label Clonezilla live
  MENU DEFAULT
  # MENU HIDE
  MENU LABEL Clonezilla live (Default settings, VGA 1024x768)
  # MENU PASSWD
  kernel /live/vmlinuz
  append initrd=/live/initrd.img boot=live union=aufs  hostname=karmic quiet noswap nolocales edd=on ocs_live_run="ocs-live-general" ocs_live_extra_param="" ocs_live_keymap="" ocs_live_batch="no" ocs_lang="" video=uvesafb:mode_option=1024x768-32 ip=frommedia  nosplash

It contains the file "live/filesystem.squashfs" which seems to be called  
somehow from the "initrd"; that looks like the Knoppix/Debian/Ubuntu way  
to boot from CD.

Yes - wrong assumption. I like to boot *.iso via memdisk - it's nearly  
no work to include a new CD.

Viele Gruesse!
