If you are willing to try, systemd allows you to set not only the
limits for opened files, but also for basically every knob the Linux
kernel has. And to set it per daemon (or unit, in systemd parlance),
of course; for what you want, you would only need to set:

LimitNOFILE=<limit>

in the [Service] section of your unit. If you are interested, all the
relevant documentation is in systemd.exec(5).
