It is possible to create custom ini file within %localconfdir%/local.d
(/etc/couchdb/local.d for instance) directory which will override
local.ini uuid option:

[couchdb]
uuid = myuuid

This file may be automatically generated with puppet without need to
edit local.ini on each instance.

That's a thought, bootstrap from something that even virtualized
systems should be wary of duplicating.

Is there something we could do with some hardware info (MAC addresses,
disk UUIDs, etc) to notice when the UUID might not have been generated
on this hardware and log a warning? Would that even be helpful?

Sure, you can do that, the trick here is knowing you need to (and,
conversely, knowing you shouldn't copy a local.ini if couchdb has
added a uuid property).
