It describes how to install freebsd on an USB-pendrive. http://typo.submonkey.net/articles/2006/4/13/installing-freebsd-on-usb-st= ick-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!
