Comment # 5 on bug 1219543 from Stefan Hundhammer

That "yast2-online-update-configuration" module is less than useless on
Tumbleweed; it gives users a false sense of security. They probably think that
their system is being taken care of with automated unattended updates in the
background.

I am not sure if it even does anything on TW. In the best case, it would simply
do a

  zypper dup

with root permissions, but if any manual interaction is needed, that would go
unnoticed, an the system would increasingly become outdated without the user
even knowing.

A RasPi doing silent tasks in the background without any system console would
be dangerously outdated very quickly if the user doesn't check it on a regular
basis; and who does that if that machine is just sitting there and apparently
working?
