Save wificheck.log to tmpfs-backed /var/log #124

Closed tiberiusteng closed 3 years ago

I have a emonpi which is used for forwarding all data from emonTX/emonTH to my server hosting Emoncms. It itself doesn't save any incoming data.

Few days earlier I login to it and discovered that /home/pi/data is still being written, and the only file with recent mtime is wificheck.log.

Given that wifi-check is only used for restarting wifi connection I think saving its log to /var/log would be OK, and this can prolong the life of SD card.

You must be running an older SD card image, on the newer images wificheck.log is written to var/log/emoncms/wificheck.log. : https://github.com/openenergymonitor/EmonScripts/blob/faf295b371d32868e1050dd2b202d8a9d397fcb3/install/emonsd.sh#L72

The EmonScripts repo contains the scripts used to build the newer SD card image.I'm afraid I can't merge this PR since it could break older images which still use the files in the emonPi repo.
