# This script makes sure that the apt sources.list and preferences from outside
# the chroot also exist inside the chroot by *appending* them to any existing
# files. If you do not want to keep the original content, add another setup
# hook before this one which cleans up the files you don't want to keep.
#
# If instead of copying sources.list verbatim you want to mangle its contents,
# consider using python-apt for that. An example can be found in the Debian
# packaging of mmdebstrap in ./debian/tests/sourcesfilter
