Heard from whom? The MSFT salesguy ;-)...

I don't know of any backdoor in SuSe or any other Linux
distribution. While it is of course possible (I haven't
reviewed the code), it is unlikely, given that the source
code is open. 

SuSe comes precompiled for various platforms. So unlike source 
based distros (gentoo, debian), you will have to do some extra
work to make sure that nothing changed in the process of 
compilation. However, the exact source code used to build SuSe
is available for review (and to rebuild it to make sure that
the binaries you got are actually based on just this source code).

Ok. this has OS trashing potential. But anybody here remember
the Microsoft 'nsa-key' fiasco ;-).
