Thanks. I could not find any clear reference to the entries in the
--exclude-from file. And I figured out that the reason I was getting an
empty archive was that -C option. I was telling tar to switch to
directory / but not telling it what to tar! Actually, in this case,
there was no reason for the -C. Taking it out got things working. One
question I have is that every so often the -v is showing things like the
tar: Removing leading '/' from member names
Well those were the first ones, and the reason I could catch those is at
that point SSH prompted my for the remote user password.
If I watch the screen (without getting sick with the fast scrolling), I
see other '/' being removed comments.
