[Dar-support] How to auto-answer "yes" in batch mode?

[Andy L. <al...@il...>]

Is there a way to force dar to answer "yes" when running in batch mode
(using the -Q option)?

I've tried option --overwriting-policy Oo
but that doesn't force overwriting ... I still get this line in the
output:
575 inode(s) ignored (excluded by filters)

Also, the dar extract finished in a few minutes, but when run manually 
takes almost an hour.

Background:
I am creating disaster recovery copies of a filesystem.  The process
involves creating a list of files, splitting that list into multiple
pieces, feed each (smaller) list to a separate dar process.  This allows
the separate dar (create) processes to run in parallel.

The recovery process must also be able to run multiple dar (extract)
processes in parallel.  Since the backup portion runs against a
snapshot, it is guaranteed there are no conflicts between dar archives;
none will have the same non-directory entry and directory metadata will
be identical in any dars that repeat a directory (which will occur 
when dar backs up the parent directories of targeted files.)
