Well, honestly, the solution I like more than the others is having the python tar bug fixed and be free to use the python tar lib. I would like to exclude cpio: it's on rpm based distro but not commonly available on others. I would like to exclude the RTFM solution, having it working out of the box. So my second choice is using a self extracting script. If you think pyar is a non standard tool, do you have considered the use of shar? Or do you think it's also a non standard tool?
