Broken path in postfix start script

In intrepid postfix 2.5.5-1, /etc/init.d/postfix contains this:

                cd $(postconf -h queue_directory)

                if [ "X$smtp_use_tls" = "Xyes" -o "X$smtpd_use_tls" = "Xyes" ]; then
                    if [ -f "/etc/ssl/certs/ca-certificates.crt" ]; then
                        mkdir -p etc/ssl/certs
                        cp /etc/ssl/certs/ca-certificates.crt etc/ssl/certs/
                    fi
                fi

As you can see, the mkdir command is missing the leading slash in the path. This makes it fail with "mkdir: cannot create directory `etc/ssl': Permission denied".
