That's because most distros don't have an active package maintainer for 
Syslinux. Debian could decide to change the name of the "isolinux" 
directory to "syslinux" and "isolinux.cfg" to "syslinux.cfg" in their 
ISO images, and it would make most things easier (while ISOLINUX would 
still work as usual). Alternative solutions are availble too.

Instead, you have to do it yourself (or by auxiliary tools that do it 
for you). This is one of the steps that Martin included:

quote (wrapped by email width):
mv /media/X-install/syslinux/isolinux.cfg 
/media/X-install/syslinux/syslinux.cfg
