I have a systemd service unit that starts a python server application.
The systemd service unit is already in a running state on the system.
I need to change some directives in the systemd service unit without affecting the running processes that this service spawned. I want to do these changes so that they will be applied when the python server application is restarted, which might be a month from now.
Is this a safe thing to do ?
Also, is it safe to run:
systemctl daemon-reload
after modifying the service unit. Will this affect the running processes that this service spawned ?
I wasn't able to find information about this in the man pages of systemd. Maybe I missed it, maybe it is safe, I don't know.
OS: CentOS 7.6
