Strangely enough rc8-rt1 boots (almost). _Exact_ same build with the
exception of the change from rt1 -> rt2. 

Haldaemon does not start on boot (fails), if I login as root and start
the haldaemon service manually it starts. And then things seem to work
fine (I'm writing this email from that machine). Still investigating...
