When I want to boot off of a raid 10, I first partition the drives
and make a small (like a gigabyte) partition 1, and put the rest of
the space on partition 2. I do this on all drives, then I create
a raid 1 of sd[abcd]1 for /, and a raid10 of sd[abcd]2 for everything
else. I've got this config on several tens of servers and it seems
to work okay.
