This is a bit off topic, but is there a good reason (other than lack of time) that cpio and pax could not be rewritten to use libarchive? Doing that would win us at least (a) a pax that correctly extracts GNU tar archives, and (b) a non-GPL cpio implementation. For the sake of completeness, it may also make sense to make shar either a C program that calls into libarchive or a wrapper around tar -Wformat=shar, but this doesn't have much practical value.
