Yes, that was my first thought but the overheads at boot time might be 
inconvenient although I'll try it to find out.

That's a good thought.

zfs as boot drive was still reletively complex to set up, in my mind at least, 
when I built this box and yes, I also thought "everything on root" possibly 
wasn't the right way to go, but I thought I'd give it a try since the handbook 
recommended it.  /home is seperate, but next build will have seperate mount 
points, whether zfs or ufs :-)
