In my 4 drive system, I'm clearly not getting 1+0's ability to use grub
out of the RAID10. I expect it's because I used 1.2 superblocks (why
not use the latest, I said, foolishly...) and therefore the RAID10 --
with even number of drives -- can't be read by grub. If you'd patch that
information into the man pages that'd be very useful indeed.
Thanks for your attention to this!
