It depends on what you mean by "better". Me, I'ld aim for
"simplest".
Here, we don't customize logging at all for named, but just let
default logging to syslog take place. For this, logrotate is
fine, as the default (delivered by RHEL) configuration includes
appropriate signalling to syslogd.
Once you get named to log directly to some file(s), you have to
take care that any rotation you set up "respects" the process
doing the logging. Otherwise (and I've only actually seen this
with Apache httpd, when something was overlooked, and httpd
happily kept logging to a deleted, but still open, file ...)
you can have some "interesting" effects. 8-)
Since named can do its own log-file management, this is probably
simplest, unless (like us) you don't need it to do any.
