[support] D7: .htaccess in temporary directory?

Dear all, On a D7 site, admin/reports/status says there should be a .htaccess file in the temporary directory. However this directory is in /tmp so outside of the docuemnt root and moreover a file there would be removed at each system startup so would have to be re-installed. Should the temporay directory for Drupal be somewhere else? Many thanks for any help about this! Shérab.
