piclone, from your description sounds like the cat's meow.  But the only 
time I actually got it to run, the pair of 32Gb cards I was using, one 
turned out to be a megabyte smaller, and of course it was the target 
card, so it crashed out, media full, and the copy wasn't usable. I 
haven't been able to even start it since, no permissions or some such 
silliness. I even removed it totally, then reinstalled it, still will 
not run because it cannot find any src to copy from, nor target to copy 
to. Its not worth a damn to me when it thinks its running in a medialess 

What it needs is brains enough to both find the media, and to quit and 
clean up when it has copied say 200 megs past the end of the data, 
regardless of the capacity of the media.

Etcher from the pine64 website looks about the same, and TBT I am 
considering pre-ordering a pair of the rock64's with 4Gb of memory, 
$44.95 each, which will start shipping the first of August. Its also 
claiming gigabit ethernet and usb3, and a sata adaptor that plugs into 
the usb3 port is a $10 bill.

IOW, same  cpu, much better gpu, and apparently lots more I/O bandwidth.

I haven't approached Bertho about it yet, but would send him one of them 
to play with if he thinks it would bypass some of the r-pi herpes sores.

More below.

rsync made a mess ( ignored filesystem diffs and boundaries) I needed a 
big mop to clean up, so after the cleanup, I did a directory by 
directory copy with the old standby, a root session of mc.
