Could whomever administrates the sup files on sup.netbsd.org add this option to
the list file for the mirror collection

symlink *

Without this, the sup for the mirror collection is following the links for
NetBSD-1.0-ports and packages and creating about 170MB of duplicated space
when I mirror sup.netbsd.org.
