Use a CompactFlash card (the board has a slot) for root, 8 drives

If booting/running from CompactFlash works, then I like this one.
Backing up root should be trivial since you can back it up into
your big storage pool. Usually root contains mostly non-critical
data. The nice SAS backplane seems too precious to waste for booting.
Do you know if it is possible to put just grub, stage2, kernel on
the CF card, instead of the entire root?
You can move some of root to another device, but I don't think you
can move the bulk - /usr.
See:

Good link.
So I suppose I can move /var out and that would deal with most (all?)
of the writes.
Good plan!
I also moved most of /opt out to save space.
This ended up being a costly mistake, the environment I ended up with
didn't play well with Live Upgrade. So I suggest what ever you do, make
sure you can create a new BE and boot into it before committing.
