I am using Red Hat's 2.2.19 kernel source package to build custom kernels
under RHL 7.0.  The builds get a lot of error messages because
/boot/kernel.h and aliases are malformed.
This file is built by fragile code in /etc/rc.d/rc.sysinit, from line 587
on.  The core of the problem is that the code tries to use the output of
"uname -r", and this is changed when I edit EXTRAVERSION in the kernel
Makefile.
This script really needs to be rethought.
Sample lines from my /boot/kernel.h:
	#ifndef __MODULE_KERNEL_package kernel2.2.19-7.0.1fs-2.2.19-7.0.1fs is not
installed
	#define __MODULE_KERNEL_package kernel2.2.19-7.0.1fs-2.2.19-7.0.1fs is not
installed 1

uname -r yields:
	2.2.19-7.0.1fs
