LVM does not make a lot of sense for this, as it would create a card that is not usable in other systems. I think unionfs fits this job, and also has the advantage of not requiring kernel replacement, only a module load. Need to add something like: insmod unionfs.ko mount -t unionfs -o dirs=/media/mmc1/usr=rw:/usr=ro unionfs /usr to startup scripts (early enough) before anything opens a file for writing under /usr.
