You run "yum update" in 1st system, it rewrites grub.conf, making new
kernel the default.

You run "yum update" in 2nd system, it rewrites grub.conf, making
it the default.

You run "yum update" in 3rd system, it rewrites grub.conf and removes
the 1st system completely :-).

etc...

On the other hand if you have a standalone grub that does nothing
but chainload each of the other systems, then each other system
is perfectly self contained, updates to the grub.conf on it only
apply to it, you don't have to fix things by hand.
