		+	* Related... I've kind of standardized on 16 or 32GB industrial cards. to back them up I use the command line tool dd:

 ** It is old and still up in Barrow in the control shed.  Still works but I sent the raspberry pis up to replace it.  My plan is to replace it with a small server with a different computer architecture this winter.  The reason for that over these small ARM processors is that I'm still trying to work around this weak telemetry problem.  Thinking that if it is an x86 (well 64 bit but that style of CPU) that we can leave a copy of loggernet running up there so that when the network goes down as long as the unit is on we are still in business.  I am working to put all of its configs in one location though.  What was unique to it that hasn't been documented yet is that it used its second ethernet port as a DHCP server in support of a PTZ web cam.  That required an additional package, special iptables rules, and some scripts in /usr/local/bin.  On the to do list to get going at some point.
