Yes, and it is not there..

Actually, I think this is probably what happened; I backed up, saw the
error, and then realized I didn't need to backup the socket dir so added
the exclusion, but then I got the error again and sent the email to this
list (not realizing I would get the error that one extra time but no
further).

And yes, this is 1.2.8.  ALL my systems are on 1.2.8.

Interesting.

The warning occurred on the first (or maybe second) backup; only once I
saw the error did I realize it was backing up a socket dir so I excluded
it.

Regardless, it's not backing up the socket dir now, and I'm not getting
the error anymore.  So all is good.

Indeed -- I had no intension to back it up, but it's not like I went
through the whole file system to find socket subdirs.  One would expect
those to be in /run, not /var/lib ;)

Thanks!
