I am quite amenable to running ZFS, I just don't want to have to abandon 
it & return to UFS if my system proves inadequate for the task, hence my 
caution about it. If I go to ZFS, I (*think* I) use it for the whole 
drives, except for swap (possibly), & slice it up into 
'partitions/slices/whatever' to do the install, right ? That was my 
take-away from reading the online pages about it. Maybe I need to 
rethink ....
