How is this "frfhsjk" user getting into the passwd file in the first place? The
reason you're getting the error is this line you are modifying is not even in
the default passwd file you are attempting to patch; it presumably is added
later on. Patching this file is not the correct way to modify it in the final
root filesystem - you need to change it in the place where the user is actually
being added.
Cheers,
Paul
