[ale] weird tgz shenanigans

[Drag0n]

the UID/GID of the creator of the package is the same number as michele
on the box your opening it on, very common. tar does not extract the
files as owned by root if root opens them, a security feature, that way
you dont open a file with 777 permitions owned as root and executable by
the world.
