I use Kubuntu, but i want to try Opensuse because of some issues with Kubuntu.

I have my home partition on a seperate partition to upgrade the system without interferance with my home partition. Do i need this also for Opensuse?

When there is an update of OpenSuse, do i need to upgrade the system or reinstall the system?

Are there things completely different between the two operating systems? (except ubuntu is using deb files...)

allready thanks.
