# Don't use dpkg-deb -x as that will error if the archive contains a file
# or directory with a setuid bit in its permissions. This is because dpkg
# calls tar internally with the -p flag, preserving file permissions.
#
# We instead only use dpkg-deb to extract the tarfile containing the files
# we want from the .deb, then finish extracting with tar directly.
