Subject: [PATCH] Provide a script that can be used to create the memstick
 images.  For now 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.
