File systems on CF

Hi,

I'm trying to determine a good file system scheme for a CF card. I will have either a 2 or 4 GB CF card to work with.

I don't want to use ext3 and mount the root partition read only because I may need to change config files. Should I use jffs2 instead? What about /var? Should I mount this in ram or use tmpfs?

Thanks,
Danny
