Does systemd by default start a service upon booting OS?












-1















https://unix.stackexchange.com/a/197682/674 says




All services are "disabled" by default; "enablement" is opt-in.




Is it correct?



After I run



sudo apt install openssh-server


why is sshd automatically run?



If a service is automatically started by systemd, how can I change the default to not start it?



Now I have installed samba server and NFS server, do I need to ask systemd to disable them by default (so that them won't automatically start every time when I boot into Lubuntu)? If yes, how?



Thanks.

  • It depends on your package manager and how is the software packaged, although in reality, sshd run in such case. Is starting on boot a default behavior? Still dependent on those. Although in reality it is the default. How to enable/disable service starting on boot? Read systemd tutorial.

  • By default, I mean the status provided by a newly installed package without any further configuration.
