Yep, it's a complete pain. You can't stabily have indexes moved to
different drives, or even different partitions on the same drive (i.e.
fastest disk area), as they're recreated in the default data location at
index time.

This was one of the things I was hoping would _somehow_ be solved with
namespaces, as in high transaction volume environments it would be nice
to have frequently used indexes [be practical] on separate drives from
the data. At present, that's not very workable.
