You can get rid of an on-disk /var alltogether. Add these lines to /etc/rc.conf: varmfs="yes" varsize="32m" It will create a memory FS for /var of 32 MB (default). You could also mount some or all of your disk partitions read-only. That's what I do on my embedded FreeBSD-driven mp3 player (running from a CF card instead of hard disk), because it doesn't have to write anything anywhere. If you have any disk partitions that you mount read+write, be sure to enable soft-updates because it tends to reduce the number of physical write operations.
