# steps to build a distribution image:
# --- here
# 1. initialize new profile (BUILDDIR) as a copy of image.in/
# 2. configure distro
# 3. copy subprofiles, script hooks, and package lists/groups
# from metaprofile to new profile (as needed)
# --- in BUILDDIR
# 4. build subprofiles and subsequently the image
