[arch-general] Start a daemon, show a syntax error

No matter I manual start any a daemon, I always see a error shown on console: /etc/rc.d/functions: line 506: syntax error near unexpected token `(' /etc/rc.d/functions: line 506: ` done < <(findmnt -mrunRo TARGET,FSTYPE,OPTIONS /) But it seem that the daemon can run correctly, so should I need to fix it and how to fix it ?
