On the latest FreeBSD installation, how can I make a partition have both /var/ and /tmp/ as a mount point? That is, one partition would contain /var/ and /tmp/. Is that even possible? I know of course that a mount point of / will contain everything not specified, but can I specifically say /dev/ad0p3/ has /tmp/ and /var/ as a mount point?

You can use one of these 2 techniques for doing this. They're highlighted in this post titled: Mount multiple directories to the same partition?.
Method #1
Boot from another system (e.g. a LiveCD) and mount your /var partition and do this as root:
cd /mnt/var mkdir -m755 .newvar mv * .newvar # won't try to move .newvar because it begins with a period mv .newvar var # rename .newvar to var mkdir -m1777 tmp # make a tmp dir Now specify a mountpoint for the entire partition in your /etc/fstab:
/mnt/ignore_me/var /var none bind /mnt/ignore_me/tmp /tmp none bind Method #2
Keep mounting the /var partition as you are currently, but do this as root:
cd /var mkdir -m1777 .tmpdir # make a hidden /var/.tmpdir NOTE: notice that /var/tmp is something different.
Add the following to your /etc/fstab, after the lines that mount /var:
/var/.tmpdir /tmp none bind
