No.

Send a feature request to ISC, or write it in yourself and maintain a patch.

Of course you know logrotate can truncate files rather than renaming them, after first copying their contents, but this leaves a small window for lost log messages.

You can also configure logrotate to work with the inactive log files created by BIND's own logging facility. That is, let BIND write and rotate log files, but then process them with logrotate afterward.

Another option is to send all log messages through syslog, which allows for:

- asynchronous (batched) file writing
- all kinds of other, more advanced features that BIND doesn't support natively
