You can, but you don't have to; you can specify it either as:

label linux-jason
	kernel vmlinuz

or what you have above.  However,

label linux-jason
	kernel /vmlinuz

... will of course not work (that goes to the root directory.)


The rule is that you have to have *all* your files (isolinux, kernel, 
and isolinux.cfg) either in /boot/isolinux, /isolinux, or / of the CD 
(as you describe above.)

No isolinux directory, and the config is called syslinux.cfg instead of 
isolinux.cfg.
