I had never named the amandatapes partition, but for this I did.  I don't know 
if its barfing on that, or the /boot name for the 0,0 partition on the first 
pata drive.

I can from here, rename either, but that isn't going to put a comment marker 
in front of those two lines at the bottom of the f8 /etc/fstab.

What we have really needed for years is a marker we can put in fstab, below 
the "gotta have it" stuff, that tells it to report in dmesg any problems it 
has with the rest of our scribbles, but since it has by then a working 
system, it should continue the boot so it can be fixed with the normal tools.

This making everything read-only (in spite of a kernel argument to the 
contrary at grub load time) so it cannot be fixed which absolutely defeats 
the purpose of its dropping you to a root shell in the first place, so why 
bother?

There is paranoia, and there is extreme paranoia, and there is BS, and this is
BS when that root shell cannot fix the error being reported.  So it looks as 
if a one character error in fstab is going to make me re-install f8 (or 
something else maybe) and recopy all that 30+GB again.  As campers go, this 
one ain't too happy about that prospect since I already have 2 days in 
this "Upgrade/Install".

So how the heck do I get that "/dev/mapper/VolGroup01" (the F8 / device) stuff 
generated or made while I'm booted to fc6, which would allow me to fix that 
from a fully functioning system?  This is the question I've asked from 
several points around the bush and which no one has addressed so far.


Linux likes to claim it doesn't have a single point of failure.  But if a typu 
in fstab doesn't qualify, I don't know what does.

Thanks John.
