Tape spanning isn't enabled, unless it is by default in the
latest release (but I don't think so).

On second look, I do not use any of the dumptypes that 
are configured for spanning.

I'd expected a switch, globally but see specific dumptypes,
I need to look into this more, I may need it soon. I have
some DLEs where an LTO 4 drive may not be large enough...
not a good setup in my mind as this also requires _large_
work areas and is tending to inhibit concurrency.

Don't get me wrong, tape spanning on my LTO drive would be
great, if I wasn't obsoleting those drives soon (don't apply
to my amanda servers that don't have jukeboxes, and my smallest
juke has LTO), but spanning on LTO4 ? That is a lot of data.
