> I don't think something as specific as deployment on a certain flavor and version of Linux should go into the Basic Product Setup Guide, but it could certainly go in the general wiki. There may already be some of this sort of thing in the old wiki. You don't need any special permissions to create/edit pages in the new Confluence server (docs.ofbiz.org), just create an account and go to the wiki space and you can create pages right away.

Makes sense.

Does anyone out there use this?  I guess I'm trying to get an idea of
how safe it is.  I suppose the answer is that it isn't really be
default and that it requires thinking about the data being handled.
How would it handle something like two orders being placed on two
different machines?  Or something with a sequenceId?
