Hello,
Thank you for your contribution.
Can you add a bit more details on your use-case? Should be ok otherwise.

FYI: There is no hot-reload of the configuration, it's just for the logs rotation.

Hello,

I would like to use logrotate to manage the rotation of transport.files logs. To streamline this process, adding the reload option to the systemd service would be beneficial. Below are the steps to configure this:

File: /etc/logrotate.d/goflow2

/var/log/sflow/goflow2/goflow2.log
{
        rotate 60
        daily
        missingok
        notifempty
        compress
        delaycompress
        sharedscripts
        postrotate
                systemctl reload goflow2
        endscript
}

Thank you!
