Is there perhaps a Fedora Wiki page on the Fedora boot process and on how to 
fix or change things at this level?  Something that goes beyond the grub 
manuals, which are too general for adequate use under any distribution (I've 
played with this on F7 and ubuntu 7.04 both, and they do things very 
differently; ubuntu, for instance, doesn't even have a grub.conf....)?

Something that describes the full boot up to the point of logging in would be 
quite useful for troubleshooting why it broke.  Something that describes how 
grub passes the boot off to the kernel, how (and why) the kernel starts nash, 
what nash does, how nash does what it does, and how init gets control and 
starts running rc.sysinit, what that does, and how the various /etc/init.d 
scripts get called (Ubuntu does it differently; a Fedora-specific doc is 
needed). Something that describes the contents of initrd, how to change those 
contents (like you need to do when you need to change the driver for the root 
filesystem's controller, if the controller's driver is modular).  
A 'Fedora-Boot-HOWTO' if you will.

The man pages for each piece are pretty good, if incomplete, but I've not 
found (doesn't mean that it doesn't exist, it just means I haven't found it) 
a complete system overview that shows where each piece fits and how it does 
its individual job in the context of the complete system.
