People have reported running arm systems using zfs in as little as 512MB (on a beaglebone), but it's a long way from "it boots" to "it's useful" and I have no idea if they were using the systems for anything other than proof of concept. I wouldn't consider using an rpi for even a moment. They're just too slow and the chipset too crippled to be useful as anything other than a toy, IMO. A Cubox (4 cores @1.2GHz, 2GB ram) should work fine. Right now your only storage option is a USB drive, (it has an eSata port but we don't have the ahci driver working on that platform yet). The freebsd-arm mailing list might get you replies from people who've been down this road themselves. -- Ian
