No. That just makes it so that if you have a failure you won't be able 
to boot, which kind of defeats the point of having a RAID array. Make 
your /boot partition a RAID1 partition right off the bat. That is so you 
can tell GRUB to boot from any of the drives. You can choose RAID10 
directly for the rest of your drive with the 5.4 installer.
