Re: [CentOS] How rc-local.service works?

Let me cite the service file here:

[Unit] Description=/etc/rc.d/rc.local Compatibility ConditionFileIsExecutable=/etc/rc.d/rc.local After=network.target

[Service] Type=forking ExecStart=/etc/rc.d/rc.local start TimeoutSec=0 RemainAfterExit=yes

I basically don't understand two things here:

1. What makes it run? Sure, when I make /etc/rc.d/rc.local executable,

it runs. But for all I know, for it to run some other service must pull in it as a dependency. Am I wrong?

It will be run according to the status of the rc-local service - i.e. what does

systemctl status rc-local

say. It's enabled by default, but it only runs if rc.local is executable (as defined in the [Unit] section).

2. Why Type=forking?

Err, because it forks! (i.e. it can leave processes running after the script has finished executing.)
