>Description:
	GENERIC kernel lacks suitable options for being used with etherboot
	(loading kernel image directly, without a boot loader such as pxeboot
	that could supply kernel parameters such as root disk name).
	This is basically BOOTP options. I'm not certain how BOOTP options
	work, but obviously, such a version of GENERIC would require variant
	that uses BOOTP (or DHCP) to acquire required data only if it is
	not already set by a boot loader.
>How-To-Repeat:
>Fix:
	Add sufficient kernel options to the configuration file after checking
	they don't override any defaults set earlier in the boot process.
