No, this is not enough. / has to be own by root for the systemd package configuration to work. So it would be: mkdir ~/tmp sudo chown root:root ~/tmp sudo sbuild-createchroot --make-sbuild-tarball=foo.tar.gz unstable ~/tmp I've just tested it successfully. And you'll have to add this line to your patch: chown 0, 0, $target or die "cannot chown $target"; Thanks, _g.
