Hello Again,
I tend to keep state as-is, require tar at host machine.
Whoever installs Fedora minimal should install tar manually.
I hope Fedora people will add tar per some of the requests, as tar is important utility in *NIX environment.
I do not think that the extra complexity is required.
If you strongly think otherwise, then I prefer to merge the self extracting python script.
Speak now, and emphasis.
Regards,
Alon Bar-Lev.
