What about when you need to share those files across a 50 node network?
I'd keep it in a database, then when I need it cache a local copy on the
filesystem. Then I can just check the timestamp in the database to see
if the file has changed. Voila, multi-node high availability images.
Seems better than have a local copy of every single image. I guess the
answer is... it depends on what you're doing!
