Hi, Two questions.
I want to raise the "number of files" limits for the user instance. First, I set DefaultLimitNOFILE to something higher than the global system default in /etc/systemd/user.conf and I rebooted. Then I confirmed that the setting has taken effect: "systemctl --user show" showed the new DefaultLimitNOFILE and the unit itself showed the higher setting of LimitNOFILE when I ran "systemctl --user show foo". So far everything worked as expected. However, when I checked "cat /proc/<pid>/limits" on the ExecStart process of foo.service, I don't see the "number of files" limit has changed. What did I do wrong? Second question: if I want to raise the limit just for a single user, how would I go about it? Making a change in user.conf would make it apply in all user instances (assuming I could get it to work). I have found that if I create /etc/systemd/system/user@<uid>.service and add LimitNOFILE to the [Service] section of that file, then it will do two things. First, it actually works whereas editing user.conf did not. Second, the change only applies to user <uid> and not all users. I assume I'm not getting how systemd is supposed to work. So please enlighten me.
