Hm yes.

I did a quick grep through sys/src/ape and apparently tar does the
following:

            switch (hdrbuf[156]) {
            case BLKTYPE:
            case CHRTYPE:
#ifndef _POSIX_SOURCE
                asb->sb_rdev = makedev(from_oct(8, &hdrbuf[329]),
                                      from_oct(8, &hdrbuf[337]));
#endif
                break;
            default:
                /* do nothing... */
                break;
            }
