I'm wondering if we should use geteuid() instead, in the unlikely event dnsdist is started with -u while in foreground mode.

How about not setting ret to "." beforehand and testing here if it's empty? If it is (somehow $HOME or pwd.pw_dir were empty or nothing worked), we could then fallback to "." before appending "/.dnsdist_history". This would prevent trying to write in "/.dnsdist_history".
