Systemd service templates (which is non-instantiated units ended with '@') currently (as of 0.5.33-alt1) are not supported by `{post,preun}_service` scripts. Making it impossible to properly restart and uninstall such instances (thus never handled in specs). Perhaps, proper support should behave something like this (for preun): systemctl --no-reload -q disable %name-server@ systemctl stop %name-server@'*'
