How to pass options to service started with systemd?

PelleP · 10-13-2014, 07:21 AM

Hello,

Ok, so Im starting to get the hang of systemd and so on on RHEL7. But I have one quick question:

If I'm for example starting the NTP-server Chrony using the command

Code:

systemctl start chronyd.service

...and I want to create only ipv4 sockets using the -4 option to /usr/sbin/chronyd. How do I accomplish that with systemctl?

If I look in the .service-file under ExecStart it says the path followed by the variable $OPTIONS. Where are the options defined?

Thanx in advance!

chrony probably has a config file that you should use instead.

Ok. Now I just used chrony as an example but is that the general answer as well?
You don't do it the way I thought, you use config files?

man systemd.exec
