Hi David;

Saving the logs to the microSD card would suffice. As needed, I can back 
them up locally to the card and to an external backup server on my 
network with ease.

My primary reason for log retention is that they are good tools for 
diagnosing issues. I've had a few strange connections that were not 
initiated by me and I'd like to be able to analyse the logs to see if 
there is a pattern. I tend to be a hacker/tinkerer that results in 
multiple reboots each week. When that happens, the logs are gone.

Thanks so much.

Is there a way to retain the systems logs between sessions? Each time
the node is rebooted, the logs from the previous session are wiped. It
would even be better if the system logs could be reopened and logging
from the new session continue in the same log files.

Thanks so much.
