Why would you say that? It's not necessary to reinstall grub when you do
a kernel update on a non-RAID system, so why do you think it's necessary
to do it on a RAID box? Once it's installed (on both disks), that should
be it. You should only need to tweak the install on the second disk when
you tweak it on the first, e.g. after installing a new version of grub
due to an OS update. Or am I missing something?
