    The easiest and quickest way to find answers to this sort of question is to use google. I just googled "cpio passthrough" and this came through as the first hit.

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
    It enables the copy-pass mode. Read this:
    3.3 Copy-pass mode
    In copy-pass mode, cpio copies files from one directory tree to another, combining the
    copy-out and copy-in steps without actually using an archive. It reads the list of files to
    copy from the standard input; the directory into which it will copy them is given as a
    non-option argument. See Options.
         cpio {-p|--pass-through} [-0adlmuvLV] [-R [user][:.][group]]
         [--null] [--reset-access-time] [--make-directories] [--link]
         [--preserve-modification-time] [--unconditional] [--verbose]
         [--dot] [--dereference] [--owner=[user][:.][group]] [--sparse]
         [--no-preserve-owner] [--help] [--version] destination-directory
         < name-list
    Sometimes, real fast is almost as good as real time.
