It was good to hear from other posters that there is nothing wrong
with, in my use case, putting data sets on same disc as rpool.

But, those comments give me pause.

I'm thinking my original setup which is in about the exact situation
you mention, is maybe still a better way to go.

I'm on OI, and it seems a good chance that either the day will come
where OI is upgradable to hipster, and hipster developers start
regular updates etc, or I will be faced with upgrading manually to
something else.  And in that case, as you say, I would be very glad
I didn't have piles of data on my OS/rpool discs.
