I execute systemctl daemon-reload after saving the slice file.
Every value is getting enforced for the user when I test them by running some commands from the user's terminal.
But they dont work after I run the same commands from the root's terminal after doing su to that user.
They also dont work when a user's process is started from a php script using putenv('user_uid');.
How do I make them work for all the user's processes no matter how they start?
Do I have add some service file in /etc/systemd/user? Please help.
