I have made a read only rootfs by giving readonlyroot as a command line parameter to kernel. The changes to etc and var depends on the applications you need. You might want to move /etc/mtab to tmpfs; one easier way is to make it as a softlink to /proc/partitions (but this makes output of mount command a bit too long). Most of the rw locations will be mounted as tmpfs by init scripts. But a few applications like dhcpd might fail. You can modify the init script to move the temporary files needed by these applications to tmpfs.
