There's really only one gotcha: if you're wanting to install the
system onto the RAID array, there's some extra steps involved.I would question the real need to do this in the first place. Using
ROOTBACKUP=1 as described in daily(8) gives you pretty much all the
benefits of RAID for your root partition without the headaches. It's a
tradeoff *I* would make, though I'm sure others wouldn't.
Is this something that I could setup during the installation process or
would I have to configure the RAID drives post-install then move
everything over to them?
