Are separate spec files a _must_? Now and in the future? I'd prefer to
manage a single file (even if there are non-fatal errors) than many. Of
course, the examples allow for a brick and brick-ns in the specification,
which makes them simple.

Might there be any interest in supporting an option which allows for a
single server volume spec file to be used but to not cause errors? E.g.,

-----
volume a
   ...
   option directory /data/a
   option hosts host-a1, host-a2
end-volume

volume b
   ...
   option directory /data/b
   option hosts host-b1, host-b2
end-volume

...
-----

The default for such stanzas would be: "option hosts *".

Thanks,
John
