If you have _anything_ about wireless interfaces (perhaps not wired ones),
it _does_ fail to start.  /usr/sbin/NetworkManager does not run.  Now,
perhaps it's because it finds no interfaces it should manage - but if so,
it should exit with a message, instead of just failing.  

Also, there's no documentation that you have to comment out the network
interfaces, nor is there any indication of how you should replace the
features that are _in_ interfaces, so everybody who uses this hits the same
