if you've just installed SuSE and not made *any* modifications to the system since install, then YOU shouldn't present problems.
where you might run into some difficulties (as I did.. see below) is if you've either updated the system using non-SuSE sources, or perhaps compiled specific drivers - eg video drivers...
I made a fresh install of SuSE 9.0, then installed the ATI proprietary video drivers, then built some drivers for the Sagem ADSL modem I'm using.
Then I decided to do a YOU update, specifically to catch security loopholes, and this included a kernel upgrade. Sure, it all installed fine, but i then had to re-install the ATI video driver and re-compile the Sagem modem driver against the new kernel - not difficult, but a potential worry....
YOU works very well, just be aware that if you've meddled with the system (as is so often necessary, particularly in the case of proprietary video drivers), you might need to do a bit of 'cleaning up' afterwards.
