How can I disable systemd messages that pop up in my BASH script once in a while (for example, after I login to the machine via SSH from somewhere), like in the screenshot below ? The BASH script uses the dialog tool and I run it on Ubuntu 18.04. One thing I tried was disabling rsyslog, but it didn't help. Here is a screenshot to illustrate this behavior: link.
My systemd service file looks something like this:
ExecStart=/bin/openvt -s -w -- /path/to/bashscript
