Update and/or upgrade - Errors

[Wolfgang Romey]

Thank you for noticing my remarks. I will try to make bug-reports in the 
future, if i find errors.

I did not find the errors earlier, as i did not know a way to update or 
upgrade an iso, so i started only the images from the stick, as i did not 
wanted to loose my home-folder.

Am i right, that i can update/upgrade via zipper refresh/update/upgrade and 
then test improvements?

It would be good, if the iso installer would offer a way to save the home 
folder.
