it isn't being integrated into 'make release' because for the forseeable future the memstick images will be identical to what's on the DVD except for which package set is provided. If/when what's on the memstick diverges from what's on the DVD it would make more sense to generate a "memstick" directory in $CHROOT/R/cdrom and build the memstick image along with the ISO images.
