Even if renamed, I'd still need a Clue as to why to prefer one scheme 
over the other. For example, I've now learned that if I want to set up a 
RAID1 /boot, it must actually be 1.2 or grub won't be able to read it. 
(I would therefore argue that if the new version ever becomes default, 
then the default sub-version ought to be 1.2.)

As to the wiki: I am not certain I found the Wiki you're referring to; I 
did find others, and none had the ringing clarity of Peter's definitive 
"RAID10 won't work for /boot."

The process I'm going through -- cloning an old amd-k7 server into a new 
amd64 server -- is something I will document, and this particular grub 
issue is one of the things I intend to mention. So, where is this Wiki 
of which you speak?
