Before Trevor suggests it, there is *always* a Perl module for it:
Archive::Tar
Which let's you rename the files inside a tarbal:
$tar->rename( $old_file_name, $new_file_name )
see: http://search.cpan.org/~bingos/Archive-Tar-2.26/lib/Archive/Tar.pm#$tar-%3El...)

Is there a way to untar a tar archive to stdout and use that output to recreate the archive by piping it back into tar? GNU tar has a transform option to change the file names.

Obviously I'll still have to un-gzip and de-cpio the whole 12GB while processing; I just don't want to put the whole thing on disk while I'm changing the path. Any ideas?
