First, turn off atime on mounts.
Add enough memory so that you never need swap. Then, use a swap file if
needed. Put /tmp on tmpfs.
Or, run a live CD like GRML and put /home on the flash drive.
Flash-drive systems are often used on embedded devices. I know that
many people use OpenBSD on their laptops and also on Soekris embedded
devices (e.g. as firewalls). You could check the OpenBSD website for
some docs and check the misc@openbsd archives.
