I took the --one-file-system option out of the options that amgtar passes 
to tar, and at least the verbose error messages are now gone.  So I ran 
amrecover Daily, and checked 2 of the 4 missing listings, and they now are 
there in the backup database, I was able to chase one of them in /var/lib 
2 more directory levels deeper than the failure point now, so I believe 
the problem to be solved in a usable manner.

However, in one failure path it quoted, there are no softlinks. It simply 
did not like /var/lib/nfs/rpc_pipefs, which actually goes 2 or 3 levels 
deeper, encountering no softlinks as it goes.

So I'm still standing here on my stump and proclaiming that tars "--one-
file-system" implementation is broken.  And has been since somewhere post 
1.22.
