I don't think tmpfs is appropriate for /var/tmp. Having it disappear after reboot violates the FHS, and along with it, many admins' expectations.
/var/tmp : Temporary files preserved between system reboots
Purpose
The /var/tmp directory is made available for programs that require temporary files or directories that are preserved between system reboots. Therefore, data stored in /var/tmp is more persistent than data in /tmp.
Files and directories located in /var/tmp must not be deleted when the system is booted. Although data stored in /var/tmp is typically deleted in a site-specific manner, it is recommended that deletions occur at a less frequent interval than /tmp.
