there's special file systems optimized for flash use, squashfs is 
readonly (its compressed at system build time) and jffs2 (aka jiffy) is 
a writeable FS designed to minimize block writes to the flash.    
Embedded Linux like used by OpenWRT on the WRT54GS and compatible 
routers uses both of these.
