[systemd-devel] : How to modify systemd so that the NTP function is disabled when systemd is first started?

[Michał Zegan]

I am not quite sure what you mean, but... generally these are symlinks
in /etc/systemd/system/multi-user.target.wants/ so you could delete them
manually if your intention is to make the actual os image with this
disabled from the start...

After I update the system, the first time I start it, time synchronization is still enabled by default. It's not appropriate if I close it alone every time. So when I need it start every time, this function is off.
