To be fair, this is a tiny update that doesn't touch too many things and uses exactly the same mechanisms as the Nokia SSUs. Rotation still works because both the kernel and X server were left alone :-)

I think the next step should be to push an updated kernel (might as well do the full rotate support though) to make sure updating that also works. It probably won't happen for a few days, but feel free to disable the SSU repository now if that makes you nervous and you wish to opt out.
