While were about this, for installs where the users select multiple partitions we currently create a separate /tmp partition. This strikes me as suboptimal, since one could use the disk space allocated to /tmp as extra swap and then allocate a tmpfs of that size to be mounted on /tmp with no effect other than allowing the system to have access to more swap than it would have otherwise had (of course, that's probably more than it needs, so instead you could just save some disk space that would otherwise be left generally unused by overloading the swap usage with /tmp usage. Therefore, in the multi-partition setup, I think we should also default to having /tmp on tmpfs.
