"Not obvious" is putting it mildly. :)

So how exactly is this supposed to work? I create the rpool, then create a
volume inside it to be used as /, another as /usr, another as /var and so
on?

And where do I then specify their mountpoints? At one point I had created
zfs filesystems manually on console 2 and set their mountpoints, but while
the "configure zfs" part of the partitioner listed them along with their
mountpoints, it didn't offer an option to change them.

I'll experiment with this about 12 hours from now, I suppose.

Thanks!
