I don't know why yet exactly why but the prefix folder in the following archive is not stripped correctly.
If I run the tar xzvf --strip-components=0 or --strip-components=1 I still get the "moodle" sub-folder. --strip-components=2 does strip it though.
If I try to run tar -tzvf you can see that all files are prefixed with "./" which might be the reasons of the difference.
ark "moodle" do
