become root user (sudo su) and then set a password for root (passwd). The
classic su will work afterwards. This is how I worked around that issue.

Nope, the Pi 2 already was / is 64 bit but at that time no 64 bit distros
(aarch64) were avaialbe for it. (Open) SuSE were the first to come up with
that.
