I've happily been using tmpfs on /tmp/ for probably ten years now, and
can list some more benefits:
- It allow diskless setups like LTSP to work the same way the default
installation in Debian work. They use read-only NFS-mounted file
systems and a writable tmpfs mounted on /tmp/.
- It reduces the number of disk writes on a laptop, allowing it to
spin down the disk a bit longer.
