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!

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. > > 1) Most of them run from SD cards or other cheap/inadequate flash media > that seems to expire very quickly when used for the rootfs.
