redmine stack?

Just signed up here after having issues on other host getting redmine configured.

stacks looks like a cool thing…. 2 questions.

can i deploy multiple stacks to each disk? maybe just havnt read enough to notice the answer…

and i dont find a stack for redmine. this is notoriously complicated, something automated would be great, any thing out there? i had especially problems running it together with other stuff on the same vps.
