I essentially followed Solid Run's wiki, which links to a binary build of
rc8. There were some issues (likely due to their usage of Ubuntu, versus
 Red Sleeve's RH conventions), but I found workarounds, which I will
document!

In my case, I got a type 10 card, in the hope that wear management will be
a little better. I put the zfs pool on two 250 GB sata drives that I had
lying around, so I may very well run into a memory issue in actually trying
to use the pool. I should note that the esata chipset on the Cubox does do
port multiplication, so the unit see both drives.

 Well, I did want to do this (in part) to become more adept with Linux :)
I'll put RPMs right behind uboot on my list.

RPMs would be good. :)

I will be shortly.
