Author: eadler Date: Fri Apr 17 18:33:59 2015 New Revision: 281661 URL: https://svnweb.freebsd.org/changeset/base/281661 Log: MFC r280206: Implement pax -O option to permit limiting a PAX archive to a single volume. -O Force the archive to be one volume. If a volume ends prematurely, pax will not prompt for a new volume.
