[Kea-users] loggers: support for file compression with enabled rotation

Wed Jun 26 12:50:57 UTC 2024

Thank you, Darren

Getting the logrotate to do the correct thing has been challenging because
of (I suspect) permissions specific to /var/log/kea subfolder. I will
continue trying but it would be certainly nice to have also support for
compression added. 75% of functionality is already in place.
