Right, I thought the mood might be "don't go bothering us with Ubuntu
issues, this is a Debian project" I'm glad that isn't the case.
My goal is to generate boot cd's with my code available, the distro
isn't a big deal, however I'm used to Ubuntu.

Right, the germane package seems to be syslinux
'aptitude search isolinux' returns
...
syslinux-common: /usr/lib/syslinux/isolinux.bin
...
and with syslinux installed, 'locate isolinux' returns
...
/usr/share/live/build/bootloaders/isolinux
/usr/share/live/build/bootloaders/isolinux/install.cfg
/usr/share/live/build/bootloaders/isolinux/isolinux.bin
/usr/share/live/build/bootloaders/isolinux/isolinux.cfg
/usr/share/live/build/bootloaders/isolinux/live.cfg.in
/usr/share/live/build/bootloaders/isolinux/menu.cfg
/usr/share/live/build/bootloaders/isolinux/splash.svg.in
/usr/share/live/build/bootloaders/isolinux/stdmenu.cfg
/usr/share/live/build/bootloaders/isolinux/vesamenu.c32
...
I've tried to follow the binary_syslinux script without success.
Would the output of
# strace -etrace=file lb binary_syslinux
be of interest?
Thanks,
Kent
Why, I don't have a clue.
