It doesn’t continuously ask for reboots.
It just shows the reboot notification before actually installing the updates instead of afterwards.
That’s a bug/limitation of the shipped Apper.
Ignore that, it is fixed with an update (which unfortunately didn’t quite make it into the 13.1 release).
Why does YasT show both ‘Add-On Products’ and ‘Software Management’ as areas to "install or remove software products’; is this an attempt to confuse?
No idea. But an Add-On Product is not quite the same as standard package Management.
** and a general note: if windows requiring passwords are put on the screen the password box should automatically receive focus. OpenSUSE KDE fails in this respect.
This generally works fine here, except for specific cases maybe (but I cannot think of any at the moment).
Do you see this with all such password windows or only specific ones?
If it’s the former, it may be caused by your stealing prevention settings. (KDE’s Systemsettings/Configure Desktop->Window Behavior->Window Behavior)
In the latter case you could create a window rule for forcing the focus for those specific windows, right-click on the window’s titlebar to reach those settings, or set up rules in KDE’s Systemsettings/Configure Desktop->Window Behavior->Window Rules.
Btw, if you experience problems, instead of complaining about it you could file a bug report against the specific application. http://bugs.kde.org/ for KDE bugs, http://bugzilla.novell.com/ (same username/password as here) for openSUSE specific bugs.
YaST > Software > Online Update (or doing similar in Sofware management) only advises me to do a reboot asap when there is a kernel update. Does most often not happen for monthes. I do not understand why it asks you on and on.
Just guessing but would not be surprised that the OP is rebooting when he sees the message rather then to wait until the update is complete then reboot. I believe that the update may correct this message that some naive users think should be acted upon immediately. If I recall.
I did not suggest that you did not make the correct assumptions with the background knowledge you have.
My comment is about the fact that the OP never mentioned what he was doing. I also use KDE, but not Apper. When he would have said he used Apper, I wouldn’t even have bothered to post a useless answer and left it to Apper users to carry on with helping.
