I vote for not having a /opt partition because binaries are in /usr and /opt.
But that means you must have a much bigger / partition, I suggest 40 GB
But I vote for either a 25 GB /var or a 20 GB /var/tmp partition (BTW the same size for /tmp),
it contains variable data and should not fill up /.
What speaks for /var/tmp (if not sym-linked to /tmp):
syslog and monitoring tools like HP-OVO need to log a disk full condition in /var. Again this means a +5 GB for the / partition.
