I would also recommend setting noexec and nosuid on /tmp (probably via
tmpmfs_flags). Just remember to allow exec again before a "make
installworld" and/or mergemaster run (and certain port installs).  :)

In my opinion, all this is part of after-installation tuning. Not sure
if that's something the installer should deal with, or you could make
many more request of post-install/tuning parameters for the installer.
