It describes how to install freebsd on an USB-pendrive. http://typo.submonkey.net/articles/2006/4/13/installing-freebsd-on-usb-stick-episode-2 It notes that /var/log /var/run and /tmp should not be written to flash memory. You can use memory devices for these directories to minimize disk writes. If you want, you can backup/and repopulate these directories on shutdown/startup. Hope it helps! Mark
