       If there is more configuration files present in the <filename>/etc/vsftpd</filename> directory, calling <command>systemctl start vsftpd.service</command> results in the <filename>/etc/rc.d/init.d/vsftpd</filename> initscript starting the same number of processes as the number of configuration files.
