I compiled the keepalived program using the source code keepalived_2.2.8 version. When I use the root user, ./keepalived -n plus other parameters will start up two processes by default, but if I command above Add sudo at the front, such as sudo ./keepalived -n and other parameters when starting, an extra process will be pulled up at this time.
The following is a comparison chart.

I hope that when I can add sudo to execute the keepalived command, a process name starting with sudo will not appear. I also want to know why this happens.
