Nice! I'm not sure the "using sudo" sentence is necessary. The recommendation is very clear! It might also be good to add a note about the --user and --group options for dropping privileges.

Should we try to recommend any reading about /etc/security/limits.conf or systemd service limit overrides?

[julyclyde]

@tilgovi Yes you are right, modifying limits.conf or using systemd unit file are also correct way besides.

I don't want to talk about external dependencies just now, just want to focus on the problem itself, so I gave my word in this PR. Maybe other words are better. Sorry for my poor English.

ulimit would definitely work for a terminal and some users so I would make the line added as a warning note to highlight it.

[julyclyde]

No, it should not work.
ulimit is a built-in command of shell, it take effect only in the shell and its children processes.
sudo ulimit would run setrlimit() in a sudo process, and then return.

[julyclyde]

You may check it in /proc//limits
