I forgot, tar default is automatic resursion that would have to be
turned off to only copy one directory. That p in the command string
does preserve file attributes like permissions though.

tony,
thanks for all this. Looking at the upgrade documentation leaves me
thoroughly intimmidated. My major reason for upgrading was to get beyond
the current kernel crash that happens a couple 3 times a week. However with
my lack of experience, I'd be pretty sure trying the upgrade would be a
bigger mess.
I'll re-evaluate the situation from time too time especially if/when they
stop supporting jessie, and see what happens.
Thanks again.
