# these might signal of file clashes (or plain dirt);
# second, care for toplevel and tagged script dirs;
# then handle two more ways of implementing a feature
#
# NB: some subprofiles will be specified as "src/dst"
#     -- then both src/ and dst/ can hold the addons;
#     still both pieces go into a single destination

### {image-,}scripts.d/ get rsynced twice :-/
