# this somewhat impenetrable and fragile code is used to build each of the images
# at build time, a few variables are set (sys, fmt, type, size, d) based on the
# target to build.  first, we build an empty image using the a tr, dd pipeline.
# we then scan the d_{d}/u* directories, copying in files to user numbers
# then process the d_{d}.txt file, copying in those files, and finally maybe put
# an OS at the start of each image
