If you are adament that you want to start slicing up your disks into
multiple pools you are probably better off ufs  for os and zfs for data as
you will have  far less hassle doing this. Having said that I have a two
pool system, on for os the rest for data and it works well. You might want
to look at installing the fbsd will the pcbsd installer as it makes the zfs
install fairly easy
