What exactly does daemon=yes do?

[rjcortese]

Hello,

I am using systemd to run pdns. The default included service unit uses the --daemon=no command line argument.
This makes me wonder, what does --daemon=yes do?

Which is the recommended way of running pdns with systemd?

Thanks

When running managed by systemd, systemd takes care of the things like backgrounding, detaching from the terminal, redirecting output streams etc.
daemon=yes is only needed when the pdns process is supposed to do these things itself.

Ah i see, in my head i was mixing them up. Thank you!
