On my 3B1, which up until now I had assumed was using the standard SV utilities,
the cpio program has an upper-case R option which is described as follows:

"Allow file and directories with absolute path names to be redirected on input
to the current directory by removing the leading / from the path name."

Does this option exist in other version of cpio and people just dont know about
it or is the 3B1 unique in this regard?
