Today that's easy to answer: Try setting up ZFS boot with a mirrored boot drive and encryption on FreeBSD, then try it on Redhat, or SLES, or Ubuntu Server. One of the experiences is very much "native" - the other is possible, but a GIANT pain to accomplish. At some point I'm sure, Ubuntu at least, will make installing to ZFS on a server OS more straightforward. I've got several systems doing it today, but I can tell you it's not for the faint-hearted and it took a TON of trial and error to get it to do what I wanted consistently. I also cringe every time I apply an update because I know it's not something that is getting any significant testing by Canonical or the community at large.
